Rounded Edges in Firefox

Extension:CSS Dropdowns allows an editor to create CSS dropdowns in MediaWiki in the MediaWiki:Sitenotice and the MediaWiki:Anonnotice when not logged in - the area at the top of the page for the entire wiki. The Wikimedia Foundation uses the sitenotice to announce elections and donation drives.

Compatibility and appearance[edit]

The extension works in Internet Explorer 7 and Firefox. This extension does not work for Internet Explorer 6 because of its poor CSS support.

The edges of the dropdowns are rounded in Firefox and Gecko based browsers. In other browsers, the box has sharp corners.


The dropdowns is pure CSS, meaning it works without JavaScript. I am trying to find a way to fix that. (I am not going to try to make it work in IE6.)

In unsupported browsers, only the top level appears, so users can click to directed to another page, but no dropdowning.

Non-CSS browsers can see all of the links in a normal unordered list. Unfortunately they will need to scroll by these on every page, making it a pain to be using really old browsers (Netscape 4.x and text-only ones, for example) as well as most cell-phones.


You need the CSS from below to power the menus. Add this css to MediaWiki:Common.css.[1].

Adding Dropdowns to your sitenotice page[edit]

To add the dropdowns, copy the following coding to your MediaWiki:Sitenotice page:

<ul id="sitenotice_nav" style="list-style-type: none; list-style-image:
 none;-moz-border-radius-topright: 1em;-moz-border-radius-topleft: 1em; 
-moz-border-radius-bottomright: 1em; -moz-border-radius-bottomleft: 1em; 
background:#F1F1CB;margin:7px -2px -2px -2px;padding:0;">
<li>[[Template:Drop Down:Pizza]]{{Drop Down:Pizza}}</li>
<li>[[Template:Drop Down:Ice Cream]]{{Drop Down:Ice Cream}}</li>

Make the pages Template:Drop Down:Pizza and Template:Drop Down:Ice Cream. On these new pages you created, use this format for your links:

*[[Cheese Pizza|Cheese]]
*[[Pepperoni Pizza|Pepperoni]]

You should now have a drop down where the top level links to the list page for Internet users and drop downs for Firefox users.

To add more links just edit Template:Drop Down:Pizza.

To add more drop downs, edit MediaWiki:Sitenotice, and add a <li> line like the example above.

You can also edit the CSS to change colors or shapes or add pictures.

Known issues[edit]

Before adding extension to MediaWiki:Common.css
After adding extension to MediaWiki:Common.css

Extension:CSS Dropdowns formats the entire MediaWiki:Sitenotice not just the dropdown, so it is not possible to have the dropdown in MediaWiki:Common.css without seriously messing up the formatting of all MediaWiki:Sitenotice.
