Frequently Asked Questions

How can I enable custom visiblity for a widget?

On Widgets editing page, each widget will have a section for controlling visibility. Enable the option “Show widget only if” to reveal and configure visibility rules (Example in screenshots).

How can I add a custom visibility rule for menu items?

New rules can be added by code in any other plugin or theme.

Example of adding a new custom rule for displaying/hiding a widget when current page is a custom-post-type.

// theme's functions.php or plugin file
add_filter('if_visibility_rules', 'my_new_visibility_rule');

function my_new_visibility_rule(array $rules) {

  $rules['single-my-custom-post-type'] = array(
    'name'      =>  __('Single my-CPT', 'i18n-domain'),     // name of the condition
    'callback'  =>  function() {                            // callback - must return Boolean
      return is_singular('my-custom-post-type');
    }
  );

  return $rules;
}

Where can I find conditional functions?

WordPress provides a lot of functions which can be used to create custom rules for almost any combination that a theme/plugin developer can think of.
