Thread:Project:Support desk/Need extension name

Hi Just recently setup mediawiki for internal use I was browsing something and saw a box inside it there was text and color. I was wondering what that extension was called.

It's similar to the language box, you have different languages to pick from. I want to create that box, where I can reference wikis from a few places I set it up on. If i'm making any sense and there is such an extension I would really appreciate it.

Thank you
