You can configure each individual Tag Cloud portlet instance separately. Use the Edit Shared Settings option from the portlet menu and configure the Tag display modes
option. You can choose between two tag display modes. Depending on the option that you select, the tag cloud displays either persisted tags or transmitted tags only. There is no option to display both types of tags at the same time. For tagging to work with social lists, you need to set this option to Transmitted tags only.
Persisted tags only
Persisted tags are served by the portal server and can include federated tags, depending on your tagging federation settings. This setting is the default setting.Transmitted tags only
Transmitted tags are tags that are transmitted by portlets on the same page. As tag transmission within the browser works without server interaction, the transmitted tags are displayed without further filtering. You need this setting for tagging to work with social lists. In transmitted tags mode, the Tag Cloud always shows the All view. Other views are not available in this mode. Users cannot switch views in this mode.
These options are added to the ones described in the topic about Configuring the Tag Cloud
in the WebSphere
Portal product documentation.
