Some months ago I created a layered diagram with multiple base layers each containing sub layers. The purpose was to hide a base layer and all sub layers would be hidden with it. For example:
- Base layer 1
- Sub layer 1a
- Sub layer 1b
- Base layer 2
- Sub layer 2a
- Sub layer 2b
By hiding Base layer 2 I also hide sub layers 2a and 2b. Now I can't remember how I created sub layers. The document clearly shows the hierarchy:
I need to add new sub layers. Can someone help me ?
