Expand Grouped Layers by Default

[lmurrayADOT]

It would be helpful to have the option for grouped layers to be expanded by default within the Experience Builder Map Layers Widget.  Ideally, it would help to select which grouped layers are expanded and which are compressed by default.  However, even just having the ability to expand all grouped layers by default would make it easier for users to locate the layer they want to view.

Our organization would also find this benneficial in recreating past web app builders to keep the change as seemless as possible for our staff.

I'd like to Second EagleAdmin and AllisonTalsma's Very Rational Observations.

Then repeat my request louder.

Adding that this functionality is very important particularly when trying to use exclusive visibility -- it's hard for a user to understand they need to expand a group layer in order to see other layers.

Definitely would enhance functionality to have this option!

On Experience Builder Developer Edition 1.15, I copied the map layers widget from "path\to\your\ArcGISExperienceBuilder\client\dist\widgets\arcgis\map-layers" and pasted it into "path\to\your\ArcGISExperienceBuilder\client\your-extensions\widgets", followed by renaming to map-layers-custom.

In the "path\to\your\ArcGISExperienceBuilder\client\your-extensions\widgets\map-layers-custom\src\runtime\widget.tsx" file starting at line 330, I updated from this:

  defineLayerListActions = async (event) => {
    const listItem = event.item
    let actionGroups = {}
    listItem.actionsSections = []

    if (this.props.config?.useMapWidget && this.props.config?.enableLegend && listItem.layer.legendEnabled) {
      listItem.panel = {
        content: 'legend',
        open: listItem.layer.visible && this.props.config?.showAllLegend
      }
    }

to this:

  defineLayerListActions = async (event) => {
    const listItem = event.item
    let actionGroups = {}
    listItem.actionsSections = []

    listItem.open = true

    if (this.props.config?.useMapWidget && this.props.config?.enableLegend && listItem.layer.legendEnabled) {
    listItem.panel = {
      content: 'legend',
      open: true
    }
  }

I then added the custom widget in and the layers were expanded by default. 

Don't forget to update the manifest.json file on lines 2 and 3. 

  "name": "map-layers-custom",
  "label": "Map Layers Custom",

Hello, Please add this functionality. Thanks!

I used this is webapp builder a lot and would like to use it in experience builder.

It would be nice to be able to pick which groups are expanded by default and which ones are not based on which datasets are commonly used or rarely used.
