There are many drives in Sites Explorer. Each drive has some views that enable you to view data in the drive in a particular way. Each view has some action tabs and each action tab contains some functions.
eXo Platform supports you some ways to view nodes in a specific folder and show actions of corresponding tab on the Action bar.
Note
The number of view types depends on which drive you are browsing. In eXo Platform, you can manage view types by selecting
--> Content --> Content Administration --> Content Presentation --> Manage View. See the Manage views section for more details.
