Collapse It is a modern Gutenberg block that allows you to collapse or expand any content area with a smooth fade effect and a customizable “Show More / Show Less” button. The block is highly flexible, letting you set the collapsed height, button styles, and texts. It also features smart empty-content detection: if the block is empty (even if it contains an empty shortcode block), it will automatically hide itself, keeping your pages clean and professional.
Key Features: 
* Collapse/expand any content with a fade effect 
* Automatically hides when empty (even with empty shortcode or any dynamic blocks) 
* Customizable collapsed height 
* Fully customizable Show More / Show Less button (text, color, alignment, border radius, font size, padding) 
* Gutenberg block editor support 
* No tracking, no ads, no bloat 
* 100% WordPress Coding Standards compliant 
* Developer: Dashboard Team

This plugin allows you to easily add “Show more…” links to your site. Just enclose the content to be hidden between <code>[showhide]</code> and <code>[/showhide]</code>. There is no modification to the backend or fancy editor. Hence the code for this plugin is minimal and the plugin should be easy to review for security issues as well not impact performance.

Show/Hide Shortcode

Small and efficient plugin implementing dynamic "Show more..." links. Just use the [showhide] shortcode, there is no addition to the backend.
