How to hide Content elements in Avia Layout Builder?

In Addition to Elliots solution, there is an easy way to remove it programmaticaly (thereby really removing a shortcode).

This example removes the button shortcode:

 function remove_shortcodes() {
/**
 * Array of shortcodes you want to remove
 * The values of this array should match the shortcode under which the elements are registered
 * Usually, you can find them in your shortcode files under $this->config['shortcode'].
 */
$shortcodes = array('av_button');

/**
 * Accepts an array of shortcodes and whether to remove these shortcodes (true) or not (false)
 */
if( class_exists('ShortcodeHelper') ) {
  ShortcodeHelper::allowed_shortcodes($shortcodes, true); 
}
}
add_action('init', 'remove_shortcodes');

However, this does not work in all contexts, so make sure to hook the function on init (or later)

There might be situations where you (or a certain user of your site) need only half of the content builder elements, and the complete content builder with all of the amazing elements is somewhat too overwhelming to a certain group of users. By limiting the amount of options, the mental ‘stress’ on the abundance of options is reduced, thereby improving the usability for a certain group of users. While this is an uncommon situation, it occurs in client practice.
