HTML5 Details Polyfill


Adds fallback support for the HTML5 <details> and <summary> elements in browsers that don’t support them using Mathias Bynens’ <details>/<summary> jQuery plugin.

Once the plugin is activated on your site, the following HTML should work in all modern browsers, even if they don’t natively support the <details> and <summary> elements:

  <summary>Click for more info...</summary>
  This is where you'd add the additional content that won't be seen until the "summary" is clicked.


Extract the zip file and drop the contents in the wp-content/plugins/ directory of your WordPress installation and then activate the plugin from the “Plugins” page.

Wordpress displays a warning that this plugin hasn’t been tested with recent Wordpress versions, but it works fine for me (Firefox 58, IE 11).
