In order to make the best use of Tag Groups, you can add your Tags to a Tag Group. 

For example, you can create a Tag Group for the Caribbean that includes Tags such as Antigua, Barbados, Cuba, etc. 

1. Select Tags from the toolbar and select the Category that your Tag Group is nested under.

2. In the search bar that reads "Search tag", enter the name of the Tag that you wish to associate with this Tag Group and then select it from the dropdown menu.

3. Once you have selected the Tag, it will appear as an option beneath the Tag Group.
