Extension:Tabs

The Tabs extension makes it possible to insert tab menus, dropdown menus, and collapsible boxes into any page, using the  and   tags, or the   parser function. This extension requires no JavaScript to work, except for older browsers such as Internet Explorer 8 and lower as a CSS  polyfill. As opposed to other extensions, this independence from JavaScript results in having no flash of unstyled content when the page loads.

Configuration parameters
None, but the default background colour for dropdown menus is stored on the "MediaWiki:tabs-dropdown-bgcolor" page.

Usage

 * See Extension:Tabs/Usage.

Bugs
Around MediaWiki core version 1.30 the extension stopped working, the code rendering into radio buttons instead of converting into tabs. See Topic:U6dfyez15vz3ya9u for the two replacement code lines to fix this.
