Tag clouds display tags associated with specific pages. These tags are displayed in the form of links and those with higher occurrence are displayed in higher font size. When a site visitor clicks on one of the links, the system displays a list of all pages with the given tag. To add a tag cloud to a page, use the Tag cloud web part.
The Tag cloud "works in pair" with a repeater web part. When a user clicks on a tag in the tag cloud, the repeater web part displays a list pages with the clicked tag. You can place the repeater either on the same page as the tag cloud or on a different page to which the site visitor is then redirected.
You can see an example of this setup on the sample Corporate Site site under Examples -> Web parts -> Tagging & Categories -> Tag cloud.
In order for the two web parts to cooperate, you have to correctly set some of their properties.
Tag cloud:
Repeater:
('{?ToInt(tagid, "")?}' = 0 AND '{?tagname?}'='') OR (DocumentID IN (SELECT DocumentID FROM CMS_DocumentTag WHERE TagID = {? ToInt(tagid) ?}))This condition ensures displaying of pages based on the received tagid (or differently named parameter) from the Tag cloud web part.
