This plugin hides the text that is defined between the simple Shortcode. By clicking on the user-defined link, the hidden text becomes visible. It works via a Shortcode and can be placed everywhere!

Usage: [show_more more=”TEXT” less=”TEXT”] Content [/show_more]
You can use some parameters like: 
– more=”show more” 
– less=”show more” 
– color=”#0066CC” 
– list=”»” 
– align=”left” | “center” | “right” 
– size=”120″

WP show more

I have tried other plugins 'read more' plugins but ended up with frustrations.. Only this one works - simple and fast. If you are looking for read more plugins, don't bother with others, just install this one.

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.
