The cloud works together with the bult in search function joomla provides. However, keyword activation must be activated backend in order for the cloud to work. This is done under "components/search/settings"
The cloud comes with settings such as,
- Two types of lists - ul li and plain.
- Maximun number of tags represented in the cloud. The number is up to you.
- Possibility to pretype some tags to your liking.
- Possibility to blacklist certain words.
The module itself have no inline styles, meaning that you control how it looks via Cascading Style Sheets (CSS). In the subnavigation you can see a few examples of how it could be setup, alongside the CSS.
