Check parent checkbox when checking child checkbox in laylerlist widget with groups of layers

[GilbertoMatos]

Hello

Is there any way that after the user clicks a child checkbox, the parent checkbox is also flagged? I created the groups of layers in the layerlist widget, using a featurecollection, and if I just check the child checkbox, without checking the parent checkbox, the layer is not displayed on the map.

Thank you!
Gilberto.

Hello

Thanks for your suggestion. Your layerlist widget looks pretty good. What happens is that I already have a layerlist custom widget, so what I need is just to make the group checkbox, that is, the father of what I checked, also be checked.

I set up groups manually using featurecollection. Before your suggestion, I tried using the "layerInfo.setTopLayerVisible (true);" statement, but I did not succeed. I did this within the "_onCkSelectNodeClick" function of the "LayerListView.js" file.

Attached, I'm including my layerlist widget. If you can take a look, I thank you.

Thank you!
Gilberto.
