We'll create fresh WordPress site with Show/Hide Shortcode installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin allows you to easily add “Show more…” links to your site. Just enclose the content to be hidden between [showhide]
and [/showhide]
. 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.
