Hello,

When i put the code in the function.php of my child theme is won’t show the search bar in the navbar.
Here is my site: durksweb.nl.
This is the code from my function.php:

/**
* This is where Customizr starts. This file defines and loads the theme's components :
* 1) A function tc__f() used everywhere in the theme, extension of WP built-in apply_filters()
* 2) Constants : CUSTOMIZR_VER, TC_BASE, TC_BASE_CHILD, TC_BASE_URL, TC_BASE_URL_CHILD, THEMENAME, TC_WEBSITE
* 3) Default filtered values : images sizes, skins, featured pages, social networks, widgets, post list layout
* 4) Text Domain
* 5) Theme supports : editor style, automatic-feed-links, post formats, navigation menu, post-thumbnails, retina support
* 6) Plugins compatibility : jetpack, bbpress, qtranslate, woocommerce and more to come
* 7) Default filtered options for the customizer
* 8) Customizr theme's hooks API : front end components are rendered with action and filter hooks
*
* The method TC__::tc__() loads the php files and instanciates all theme's classes.
* All classes files (except the class__.php file which loads the other) are named with the following convention : class-[group]-[class_name].php
*
* The theme is entirely built on an extensible filter and action hooks API, which makes customizations easy as breeze, without ever needing to modify the core structure.
* Customizr's code acts like a collection of plugins that can be enabled, disabled or extended.
*
*/

/**
* The best and safest way to extend Customizr with your own custom functions is to create a child theme.
* You can add functions here but they will be lost on upgrade. If you use a child theme, you are safe!
* More informations on how to create a child theme with Customizr here : http://themesandco.com/customizr/#child-theme
*/

/**
* The tc__f() function is an extension of WP built-in apply_filters() where the $value param becomes optional.
* It is shorter than the original apply_filters() and only used on already defined filters.
*
* By convention in Customizr, filter hooks are used as follow :
* 1) declared with add_filters in class constructors (mainly) to hook on WP built-in callbacks or create "getters" used everywhere
* 2) declared with apply_filters in methods to make the code extensible for developers
* 3) accessed with tc__f() to return values (while front end content is handled with action hooks)
*
* Used everywhere in Customizr. Can pass up to five variables to the filter callback.
*
* @since Customizr 3.0

I got the searchbox in the navbar but now the seachbox is not clickable.
This is the code in the header.php:

If i put the code <div class=”navbar-wrapper clearfix row-fluid”> in the header.php the seachbox works but then the menu is not clickable.
Something is going wrong.

Then there is another thing. When i hide the navbox lilke mentioned in the snippet remove-navbar-box the searcbox is vissible and when i want to show the navbox the searchbox is gone.
Here is my site: durksweb.nl.

behmtt: you should not be editing core Customizr files like this. Did you read the link I gave above?

Hello Sevar,
i did succeed in getting the searchbox in the navbox. But with possitioning the searchbox witch css it was either not clickable or the the menu was not clickable. So i give up and placed the searchbox in the footer.

Hello – I used the php and CSS in my child theme as instructed above and it is really close but the search bar is a little above my menu items. What do I need to fix to make it line up?
