Kodlo Product Gallery for Elementor

Changelog

2.9.0

• Feature: Fully documented inline style usage with robust justification comments and PHPCS ignores to comply with WordPress.org guidelines.
• Fix: Added pre-initialisation slide margin rule to match Swiper’s default gap on mobile, preventing adjacent slide slivers from peeking through due to subpixel rendering before Swiper boots.

2.8.1

• Fix: Fixed pagination pre-initialisation height rule to prevent double-spacing margin layout shifts when Swiper loads.
• Fix: Neutralised CSS grid gap on mobile flex wrapper to prevent cumulative Swiper slide offset during swiping.
• Verification: Confirmed independent device settings for image zoom/magnifier, and validated grid layout locking (disabling swiping gestures) on desktop viewports.

2.8.0

• Optimization: Unified the desktop grid and mobile slider into a single Swiper HTML container structure to prevent grid flashing (FOUC) on mobile devices, eliminate duplicate DOM nodes, and support dynamic custom breakpoints.
• Fix: Restored clean, standard inline dynamic CSS tag rendering inside widget markup for instant layout parsing and FOUC prevention.
• Fix: Generated visibility and layout rules dynamically using configured Elementor breakpoints instead of static media queries.
• Fix: Neutralised CSS grid gap on mobile flex wrapper to prevent cumulative Swiper slide offset during swiping.
• Fix: Added pre-initialisation full-width slide rule to prevent adjacent slide slivers from peeking through before Swiper loads.
• Fix: Restored original mobile edge-bleed CSS with clip-path idle/active transitions and wrapper stretching, fully compatible with the unified structure.
• Fix: Removed static slide display/width overrides from the global stylesheet and moved them into desktop-only dynamic CSS.
• Fix: Removed inline display grid style override from JavaScript boot and simplified device-range detection.
• Fix: Updated hover magnifier script selectors and device checking to support the unified slider container.
• Fix: Solved JavaScript syntax error (unexpected token ‘)’) in frontend widget script.
• Compatibility: Updated Elementor desktop style controls to map gap, border-radius, lens, and border settings to the new unified classes.
• Compliance: Replaced fallback dynamic CSS output in wp_footer with a fully-compliant enqueued virtual stylesheet using wp_add_inline_style.
• Maintenance: Renamed translation files (uk, de_DE) to match the correct text domain kodlo-product-gallery-for-elementor.
• Fix: Added missing resource version parameter to virtual stylesheet registration to prevent caching warnings.
• Clean: Reviewed stylesheet for dead code or duplicates.

2.7.9

• Feature: Added “View details” link in the plugin row meta on the Plugins list page.
• Compliance: Replaced inline <style> tag with wp_add_inline_style() + wp_footer fallback for per-widget dynamic CSS – addresses WordPress.org enqueue guidelines.
• Compliance: Added esc_attr() escaping to all boolean ternary outputs in HTML attributes and class values.
• Fix: Removed UTF-8 BOM from all PHP files – fixes “15 characters of unexpected output during activation” error and stray  characters in rendered HTML.
• Compliance: Added woocommerce to the Requires Plugins header so WordPress 6.5+ enforces both Elementor and WooCommerce as required dependencies before activation.
• Maintenance: Renamed plugin folder and main file to kodlo-product-gallery-for-elementor to match the WordPress.org plugin slug.
• Maintenance: Updated translation files (uk, de_DE) to version 2.7.9 with new “View details” strings.

2.7.8

• Maintenance: Unified ABSPATH security guard to defined( 'ABSPATH' ) || exit; across all PHP files, replacing the multi-line if-block form used in include files.
• Maintenance: Renamed all PHP include files to carry the kodlo-elementor-gallery- prefix, consistent with WordPress plugin naming conventions and easier to identify during profiling.
• Maintenance: Renamed all JS and CSS asset files to include the kodlo-elementor-gallery- prefix for easier identification in browser developer tools.
• Fix: Removed duplicate Ukrainian translation files (uk_UA.po / uk_UA.mo) – the correct WordPress locale for Ukrainian is uk, not uk_UA; the files were never loaded by WordPress.
• Maintenance: Added missing POT translation template file (kodlo-elementor-gallery.pot).
• Cleanup: Removed orphaned mobile-edge-bleed.php controls file – its controls had been merged into General settings in a previous release but the file was not removed.

2.7.6

• Fix: Merged separate Product Variations toggles (desktop/mobile) into a single control in General settings – the setting was split but both desktop and mobile always mirrored the same intent; the unified control removes the redundancy and the two orphaned description strings from translations.

2.7.5

• Cleanup: Normalized boolean data attributes – show_pagination, mute_videos, loop_videos, loop_mobile now use yes/no strings consistent with all other boolean attributes; removed the dataBool() helper that existed solely for the old true/false format.
• Fix: Moved Featured Image toggle from Desktop view settings to General settings – the control was conditioned on desktop view being enabled but its logic applied to both desktop grid and mobile slider; it is now always visible and correctly reflects its global scope.

2.7.4

• Feature: Added Image Loading Optimization setting in General settings – disabled by default. When enabled, exposes configurable per-context priority image counts: desktop grid, mobile slider, and mobile thumbnails separately. First N images receive fetchpriority=”high” decoding=”async” (LCP), remaining images receive loading=”lazy” decoding=”async”. When disabled, no loading attributes are added.

2.7.3

• Perf: Gallery images now carry correct loading optimization attributes – the first image in the desktop grid and mobile slider each receive fetchpriority=”high” and decoding=”async” (no lazy loading) to support LCP, while all remaining gallery images and all thumbnail images receive loading=”lazy” and decoding=”async”. Attributes are set explicitly rather than relying on WordPress or Elementor counters, which may already be consumed by other page elements before the gallery renders.

2.7.2

• Fix: Mobile slider slides are no longer clipped in the Elementor editor – Elementor Pro’s widget-nested-carousel.min.css applies overflow:hidden via .swiper-container:not(.swiper-container-initialized), but Swiper 8 only adds swiper-initialized (not the Swiper 6 legacy class). After Swiper initializes, the legacy class is now added to both the main and thumbnails slider elements to neutralize the conflicting rule.

2.7.0

• Fix: Added missing translators comments for esc_html__() calls with %d placeholder in widget-render.php – split ternary into if/else so each comment sits immediately above its translation call.

2.6.9

• Fix: Pagination dots and magnifier button now reinitialize correctly after changing widget settings in the Elementor editor – moved elementorFrontend.hooks.addAction registration inside jQuery(window).on(‘elementor/frontend/init’) so it runs after elementorFrontend.init() completes and hooks are guaranteed to be available. The previous synchronous check ran before init() and silently skipped registration.
• Cleanup: Removed orphaned var renderedMaxImages declaration left over from the 2.6.8 dead-code removal.

2.6.8

• Cleanup: Removed no-op on.init Swiper callback for updateLimitedPagination – the call fired synchronously before browser paint so getBoundingClientRect always returned 0; the requestAnimationFrame call below it is the sole effective path.
• Cleanup: Removed dead code branch in initializeGallery – currentMaxImages and renderedMaxImages both read from the same PHP data attributes so the condition was always false.

2.6.7

• Fix: Pagination dots and magnifier button now appear immediately after changing widget settings in the Elementor editor – added elementorFrontend.hooks.addAction for frontend/element_ready directly in frontend.js (inside the preview iframe context) so the hook registration and dispatch share the same hooks object. Registration is guarded with isEditMode() so production frontend is unaffected.

2.6.6

• Fix: Resolved Swiper instance leak in the Elementor editor – getInstanceKey now uses the stable widget data-gallery-id so destroyMobileSwiper correctly cleans up the previous instance on every re-render instead of accumulating orphaned Swiper objects with live window/document listeners.
• Fix: Corrected the editor reinit debounce – the timer is now stored on the stable scope element rather than the replacement wrapper element, so rapid setting changes are properly debounced and the wrapper lookup is deferred until the timer fires to always target the current DOM node.
• Fix: Replaced the window load wrapper for element_ready hook registration with a DOMContentLoaded + load dual listener and a registered guard, ensuring the hook is always registered at the earliest safe moment.

2.6.5

• Fix: Pagination dots now appear immediately after widget re-init – deferred the initial updateLimitedPagination call to requestAnimationFrame so bullet dimensions are measured after browser paint rather than synchronously during Swiper construction.

2.6.4

• Fix: Pagination dots no longer disappear after changing Thumbnails Per View or other settings in the Elementor editor – stale bullet DOM is now cleared before re-initializing Swiper (editor only).
• Fix: Magnifier now activates immediately after widget settings change in the editor without requiring a viewport switch – refresh is called after Swiper finishes creating its slides (editor only).
• Fix: All mobile slider images now load reliably after a settings change in the editor – Swiper preloadImages and updateOnImagesReady options are enabled on reinit (editor only).
• Fix: Rapid successive widget setting changes in the editor now trigger only a single gallery reinit – a 150 ms debounce prevents redundant reinit calls from the Elementor element_ready hook (editor only).

2.6.3

• Performance: Magnifier CSS and JS (magnifier.css ~4.5 KB, magnifier.js ~9.5 KB) are now loaded only when the Magnifier image effect is selected for desktop or mobile view – saving ~14 KB on every gallery instance that does not use magnifier.
• Performance: Edge Bleed CSS and JS (edge-bleed.css ~1.2 KB, edge-bleed.js ~1.6 KB) are now loaded only when Mobile Edge Bleed is enabled – saving ~2.8 KB on instances that do not use the feature.
• Performance: Removed magnifier.css and edge-bleed.js from the hard dependency chains of frontend.css and frontend.js so that the base styles and scripts no longer pull in feature-specific assets unconditionally.
• Maintenance: In the Elementor editor and preview context all assets are still loaded unconditionally so that live setting changes take effect immediately without a page reload.

2.6.2

• Fix: Resolved horizontal page scroll caused by overflowing adjacent Swiper slides in Edge Bleed mode. The wrapper now expands into the gutter (overflow-x:clip prevents scroll) while slider-wraps are pulled back to content column width via compensating margins, so images do not stretch and screen-edge nav arrows remain within the clipping boundary.

2.6.1

• Fix: Replaced the wrapper-expansion Edge Bleed layout with a clip-path-only approach – the gallery wrapper stays at content column width, and adjacent Swiper slides bleed through via overflow:visible and a negative-inset clip-path transition, eliminating the image and thumbnail stretching introduced in 2.6.0.

2.6.0

• Fix: Replaced the Edge Bleed margin/padding layout technique with a position-relative offset and explicit width calculation, eliminating the visible right-side gap that appeared on width:100% elements inside Elementor columns.
• Fix: Edge Bleed structural CSS now applies only when mobile view is enabled; the media query is omitted when desktop view is disabled so Edge Bleed works correctly in mobile-only mode at all widths.
• Fix: Mute Videos control now hides only when Autoplay is set to Both; the control remains visible for Desktop-only or Mobile-only autoplay so the manual mute setting can apply to the view without autoplay.
• Fix: Corrected the mute render logic so autoplay forces mute only when set to Both, matching the updated control visibility behavior.
• Enhancement: Moved the Navigation Arrows Padding control outside the Normal/Hover tabs and placed it directly after Icon Size for both Main Slider and Thumbnails arrow groups.
• Change: Desktop View Settings is now the first section in the Content tab; General Settings moved to the end.
• Change: Desktop Style Settings is now the first section in the Style tab (no top separator); General Style Settings moved to the end.
• Maintenance: Removed columnar alignment spaces from variable assignments across all plugin PHP files.
• Maintenance: Simplified the mobile breakpoint fallback from a multi-line Elementor API block to a single null-coalescing expression with a 768px default.

2.5.6

• Fix: Corrected the Normal, Hover, and Active pagination dot color variables so widget colors and Elementor Global Colors reach the frontend styles.
• Fix: Routed pagination dot colors exclusively through widget-scoped CSS variables while retaining theme-resistant frontend priority.
• Maintenance: Removed unused maximum-dot and positive Edge Bleed gutter CSS variables.

2.5.5

• Change: Replaced the Navigation Style and Video Style tabs with conditionally displayed labeled control groups.
• Change: Moved Video Icon on Thumbnails from Mobile View Options to Video Options.
• Fix: Strengthened pagination dot styles against theme overrides and prevented hover styles from overriding the active dot.
• Translation: Removed obsolete tab labels and synchronized German and Ukrainian catalogs.

2.5.4

• Enhancement: Reorganized Video Style settings into conditionally displayed Gallery and Thumbnail tabs while preserving existing control values.
• Change: Updated mobile magnifier button defaults to an 18px icon, top-right position, 10px padding, zero margin, and a 20px bottom-left radius.
• Enhancement: Moved mobile pagination dot styles into Navigation Style and separated image, thumbnail, and dot navigation controls.
• Enhancement: Moved mobile navigation content controls into a dedicated Navigation section and control file.
• Change: Consolidated main and thumbnail Edge Bleed arrow anchoring into one Navigation Arrows Edge setting.
• Translation: Synchronized German and Ukrainian catalogs with all current plugin strings and rebuilt the MO files.
• Maintenance: Completed a release audit of controls, runtime attributes, metadata keys, translations, and packaged assets.

2.5.3

• Change: Removed the Edge Bleed Exit Direction option and its outward mask animation, retaining the standard reverse animation.
• Change: Removed the Transition Easing option and standardized Edge Bleed transitions on ease-out.
• Enhancement: Kept separate configurable reveal and hide durations for Edge Bleed animations.
• Fix: Unified the selected Elementor video icon across video posters and video thumbnails, including variation gallery rebuilds.

2.5.2

• Enhancement: Added separate reveal and hide durations for Mobile Edge Bleed, both defaulting to 200ms.
• Feature: Added Reverse Inward and Continue Outward exit directions for side images after a swipe.

2.5.1

• Feature: Added a separately configurable active magnifier button icon, with a search-minus icon as the default.
• Enhancement: Added configurable duration and easing for smooth Mobile Edge Bleed appearance and disappearance.
• Fix: Replaced unsupported nested Elementor tabs in the mobile magnifier button controls with clear state headings.

2.5.0

• Feature: Added optional Mobile Swipe Edge Bleed for the main slider and thumbnail carousel, disabled by default.
• Feature: Added a configurable Mobile Side Gutter with a 30px default and independent Content Edge or Screen Edge anchoring for main and thumbnail overlay arrows.
• Performance: Added a pre-Swiper thumbnail layout for the configured 2-5 thumbnails per view, reducing the initial full-width thumbnail flash and mobile layout movement.
• Change: Removed plugin-specific LCP controls and custom fetchpriority, loading, and decoding overrides so Elementor and WordPress can manage page-level image loading optimization.
• Markup: Removed empty inline style attributes and output data-video-url only for gallery items that contain video.
• Maintenance: Moved edge bleed controls, behavior, and styles into dedicated PHP, JavaScript, and CSS modules and added concise CSS section comments.
• Documentation: Rebuilt the plugin description, feature overview, FAQ, screenshots, and accessibility wording around the current implementation.

2.4.1

• Enhancement: Added an optional, styleable video indicator to mobile thumbnails.
• Enhancement: Changed the maximum visible dots setting to an integer slider from 2 to 10.

• Enhancement: Added Lens and Button tabs with full mobile magnifier toggle icon, layout, normal, and hover styling controls.
• Fix: Kept the pagination fade inside the exact configured dot window so adjacent dots no longer leak into view.
• Fix: Ensured active pagination colors and borders take priority while hovering the active dot.

2.4.0

• Feature: Added configurable Zoom Factor slider (0-3x) for both desktop and mobile Zoom effects, replacing the fixed 1.08x scale.
• Feature: Added configurable Zoom Factor slider (0-3x) for both desktop and mobile Magnifier effects, replacing the hardcoded 2x zoom level.
• Feature: Added Lens Size slider (px) for both desktop and mobile Magnifier effects, with independent defaults (160px desktop, 140px mobile).
• Feature: Added Lens Border Style, Border Width, Border Color, and Border Radius controls for both desktop and mobile Magnifier effects.
• Enhancement: All zoom and magnifier values are now stored as CSS variables scoped to each widget instance, ensuring independent settings across multiple widget placements.
• Fix: Migrated dot color controls (normal, hover, active – background and border) to CSS variable selectors, ensuring Elementor Global Colors are respected correctly instead of being overridden by the base stylesheet’s !important declarations.

2.3.0

• Feature: Added mutually exclusive None, Zoom, and Magnifier image effects with independent desktop and mobile settings.
• Enhancement: Added a lazy-loaded desktop pointer lens and an accessible mobile magnifier toggle with drag interaction.
