Hi MRachlewicz,

We will need to check your site live so please share your website login credentials so I can test this. To safely include your credentials click the Insert Credentials button in the editor toolbar (see how), or you can create a temporary login without a password (see how).

Hi again,

1. Under Laborator > Typography > Function Pro I have added the custom selector for sub-menu where I have set the font size to 18px:

(view large version)

While if you want to change the menu color you can change the colors in Theme Options but if you want only for the menu then use this CSS:

.standard-menu-container.menu-skin-main ul.menu > li > a {
    color: #0000ff;
}

2. I have downloaded the Polish translation since Kalium is already pre-translated in 18 languages, the translations usually show under WordPress > Updates so I downloaded from there and the search placeholder is now in Polish.

3. Can you please be more specific, do you have an example of this?

Hi again,

3. It’s currently not possible to add a sliding or fixed menu specifically for a single page like https://puroclinic.pl/sample-page/ directly through the theme options. The method you’ve used, by creating the menu with an accordion and adjusting widget settings, is the appropriate solution for having an additional menu on that specific page. 

4. I've added this custom code in functions.php file to shorten the length of post excerpt retrieved by WPBakery post excerpt attribute and it worked, so all you have to do is to set your preferred number of words which I set 20 as an example:

/**
 * Trim excerpt length for WPBakery Grid Item attribute "post_excerpt".
 */
add_filter( 'the_excerpt', function( $excerpt ) {
    if ( wp_doing_ajax() && 'vc_get_vc_grid_data' === $_REQUEST['action'] ) {
        return wp_trim_words( $excerpt, 20 );
    }
    
    return $excerpt;
} );

5. Slider Revolution, Advanced Custom Fields, WPBakery Page Builder and Layer Slider are premium plugins that theme authors purchase extended licenses of them to be able to include those plugins on our theme for free. So you can use those plugins without any problem. Those plugins may offer some extra features that are activated only if you purchase a copy of those plugins. Then you also get the support for those plugins if you need support from the author.

We also wrote about this on many pages of our documentation site.

• https://documentation.laborator.co/kb/kalium/slider-revolution
• https://documentation.laborator.co/kb/kalium/wp-bakery-plugin-introduction/
• https://documentation.laborator.co/kb/kalium/layerslider-plugin/

To sum this up, they are free and there is no need to purchase a license to use their functionality. They have added extra features later and did not allow theme authors to include them in themes, that's why these "registration" or "license key" parts show in these plugins.
