A tag cloud (or weighted list in visual design) is a visual depiction of content tags used on a website. Often, more frequently used tags are depicted in a larger font or otherwise emphasized, while the displayed order is generally alphabetical. Thus both finding a tag by alphabet and by popularity is possible. Selecting a single tag within a tag cloud will generally lead to a collection of items that are associated with that tag.

So here is the XMod tag cloud, it's a tag cloud that is populated by XMod form data and is used to navigate and filter an XMod list.

 If you have any feedback please use the tag cloud forum, if you have any suggestions please use the products feedback centre.
