Nested Layer Control?

[Ricky Satomi]

Is there a way to have nested layer control options?
Possibly through linking layergroups with the individual layers

The objective is to display data in a more organized manner. In theory, selecting the "fast food places" layer would activate all tree sublayers. The user could then turn off the "mcdonalds" and "jack in the box"  layer to just show the "burger king" layer.

Fast Food Places
- Mcdonalds
- Burger King
- Jack in the Box

This plugin is half way there:

You could probably modify it so there is a checkbox next to "Random" and "Landmarks" (in their example) which would switch on/off the sub layers.

Alternatively, create a layerGroup with all your fast food layers and add it to layer control. 

Then add some checkboxes for each restaurant which add/remove these layers from the layerGroup.
