Expand grouped layers in Layers Widget by default - Experience Builder (ExB)

Hi All,

Are you able to expand grouped layers in the Layers Widget in Experience Builder (ExB) by default? And further to that, can you expand some by default and keep others collapsed? Thanks.

Jamie.

I understand this could be possible with custom widgets in the Developer Edition of ExB, with some coding:

Alternatively, please feel free to post this in ArcGIS Experience Builder Ideas as well:

In the LayerList , in

listItemCreatedFunction: (event) => {

you should be able to set:

if (item.layer.type == 'group') {

item.layer.ariaExpanded = true <<not working?

item.layer.open = true << not working??

item.layer.title= "this is a group" << rename your group layer

item.layer.visible= false
item.visibilityMode: "exclusive" << make children radiobuttons

item.layer.listMode = 'hide' << this hides the legend patch
item.panel.open = true << ?? not sure ??

I know this is an older post but this is a feature I could use. It didn't look like anyone added this to the ArcGIS Ideas website so I went ahead and created one. https://community.esri.com/t5/arcgis-experience-builder-ideas/expand-grouped-layers-by-default/idi-p/1310073/highlight/true.

This is supported now in the Map Layers widget with the recent Feb 2025 AGOL release:

This is really helpful, however it would be even more helpful if the user can set which specific layers are to be expanded, not just all.
