 * Is there a way to get Cumulative Layout Shift under control?
 * Hidden sections are unfolded for a short time when the page is loaded.
    This 
   creates a layout shift that can be very large and unattractive depending on the
   length of the content.
 * Is there a way to counteract this?
 * Best regards

 * This is because there is a) a large amount of content on your page b) the page
   has a longer load time c) the server is slow.
 * The plugin will wait until the page finishes loading before the initial collapse.
   This is so that the indexing robots from search engines can properly crawl and
   index the hidden content.
 * To force the hidden content to be hidden on page load, assign the _maptastic_
   class to the target using the _targclass_ attribute like so:
 *     ```
       [expand title="trigger text" targclass="maptastic"]hidden content[/expand]
       ```

 * The class works.
