Group Layers in Layer List Widget

NathanHeickLACSD — Mon, 21 Sep 2020 21:38:35 GMT

Does anyone have any ideas on how to take a long list of feature layers in your web map and group them? I want the groups to have check boxes like a regular layer.

Thanks,

Nathan

Hello.
You could perhaps make groups on map level, before to publish your portal.
Otherwise you could/should probably edit the LayerList widget.

I made a change not in order to group layers as you want, but to add section titles between layers.
I made this in ...\widgets\LayerList\LayerListView.js, under drawListNode function.
It's probably were you should have a look.

Best regards and good luck

Thanks! I will look into it. I also found some ideas from Xiadong Wang from Esri in another question. There is also an item out on the Internet from Innovate Inc. for a GroupedLayerListWidget. I'm going to try to go through them all and understand them. Thanks again.
