Forum Groups Properties
By default, the Forum Groups can be collapsed or expanded by clicking anywhere on the Forum Group bar. All Forum Groups created within the current Team will also be displayed. However, it is possible to be selective as to which Forum Groups should display on each Channel within the Team. For example, you may have a Channel within your Team that is intended specifically for Online Marketing. Therefore, you could add Social Squared to the Online Marketing Channel and choose to only display the Online Marketing Forum Group.
To show specific Forum Groups, select one or more forum groups from the Forum Groups drop down. Deselecting all forum groups will display all forum groups.
The same property can be used in Microsoft SharePoint pages. It may be that you would like to mask out some Forum Groups on a SharePoint page, and you can do so with the same Forum Groups property.
