Hiding 'groupness' of TileLayers inside Layerlist

LeidavanHees — Wed, 01 Feb 2023 09:17:37 GMT

Hello,

I have a layerList with legend that works beautifully for normal layers and groups. But I'd like it to show tileLayers as normal layers instead of groups.

Currently it does this (only "Groen" is a group, the rest are tileLayers):

It looks the same if I open the map in the esri map viewer:

Is there any way for me to change this so that the tileLayers do not have the arrow to open them? Or should I just not work with tileLayers?

Any help would be much appreciated!

Hi @LeidavanHees ,

You can hide the sublayers with the listMode property set to "hide-children" on the layer.

const layer = new TileLayer({ url: "https://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer", listMode: "hide-children" }

Thanks for your response @Sage_Wall. I think I'm missing something though.

I don't make any layers in my app, I just load a webmap that happens to have TileLayers in it:

Is there a way to do this still?

I haven't tested the code below but I think something like this would work to loop through the webmap's layers and if the layer type is "tile" then set the listMode to "hide-children". If I get a chance later today I'll try to work up a working example.

That works like an absolute charm, thank you very much!

I case anyone needs this in the future. It works even better when using allLayers instead of layers:

Since that also fixes it for any tileLayers inside of groupLayers
