<h2 class="wp-block-heading" id="query-string">Query String</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>You can set visibility by query string. For example, this is regular url - site.com/your_post  and this is url with query string site.con/your_post?filterby=id</p>

<!-- wp:paragraph -->

<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>You can show/hide blocks related to gadget of user. This option is different from Responsive control, which can hide only visibility of block via CSS and width of browser (but block is still on page). Visibility by Mobile view uses dynamic render so blocks are not existed on page if user uses mobile. This option uses wp_is_mobile function</p>
<!-- /wp:paragraph -->

<!-- wp:heading -->
<h2 class="wp-block-heading" id="by-cookie">By Cookie</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>You can hide/show blocks related to user's cookie. Greenshift has also several blocks which can save cookie. For example button block and switcher blocks. So, you can use button block and save special cookie on user's click and use visibility block to show/hide conditional blocks related to user's choice. </p>

<h2 class="wp-block-heading" id="change-visibility-programmatically">Change visibility programmatically</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>You can also use special PHP filters to check visibility per separate block.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>First of all, copy ID from visibility's block Panel. For example, it will be "gsbp-0fcead2"</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Now you can use next code</p>
<!-- /wp:paragraph -->

<!-- wp:code -->
<pre class="wp-block-code"><code>add_filter('render_block', 'custom_visibility_conditions_check', 11, 2);
function custom_visibility_conditions_check($block_content, $block){
     if(isset($block['attrs']['id']) && $block['attrs']['id'] == 'gsbp-0fcead2'){
}
     if(is_home()){
          return '';
     }
     return $block_content;
}</code></pre>
<!-- /wp:code -->

<!-- wp:paragraph -->
<p>This code will add extra condition layer that checks if block is on homepage, if yes, it shows nothing (hide content).</p>
