@ercangulcay Thank you for your review.
Please tell us which page you are referring to? We would appreciate it if you could provide a link to this page or describe in detail which page of the site it is.
In fact, you can use the filter on multiple pages at the same time. For example, on all WooCommerce shop pages or on all Blog archive pages. In the next update, we plan to add the ability to use the filter on Singular pages as well.
After setting up all the filters, I wanted to use the shortcode at the top of a single page. I wanted to filter portfolio items. After adding the shortcode to the page, I saw that this isn’t supported on single pages. It wants me to purchase the Pro version. The Pro features are not sufficiently described on the plugin’s introduction page. It was an unnecessary expense in my limited time. Please describe in more detail on the introduction page what can be done with the free version.
