You can store groups within each other to create sub-groups. This can be useful when you want to organize less important scene elements or actions within another heading.

To create a group:

1. Select an existing group in the Scene browser.
2. Drag it on top of a second group.
3. Select Move to Group from the contextual menu.

The first group becomes a sub-group of the second.

You can also copy a group to another folder by selecting Duplicate to this Group from the contextual menu. This leaves the group where it is and adds it to another group at the same time.

To remove a sub-group:

1. Select a sub-group in the Scene browser.
2. Drag the sub-group on top of the Groups root folder.

   The sub-group then displays under the root folder as a regular group again.
