I have a Group Layer, and am using the LayerList widget. By default, I have all of the sub-layers in the Group Layer turned Off (visible: false). Thus when a user clicks on the Group Layer (in the LayerList) nothing happens - they have to expand the Group Layer to see the contents and then turn the individual layers On.
I would like to remove the option to turn the Group Layer On / Off (since clicking the On / Off eyeball is confusing since nothing happens when the user clicks the eyeball). Instead I would like the Group Layer name to simply be a heading that can be expanded / contracted to expose the sub-layers.
Essentially, I just want the Group Layer to be always On (with the sub-layers still off by default).
So, rather than seeing:
> (eyeball) Transportation
(eyeball) Bus Stops
(eyeball) Bike Routes
I want to have:
> Transportation
(eyeball) Bus Stops
(eyeball) Bike Routes
* Edit / Addition: If it makes a difference, ALL of the items in my LayerList could be Group Layers. So maybe there is a way to just have an expandable List of Group Layers...?
Anyone have any suggestions? Or some other way to create a simple group layer w/a header?
thanks,
