How to add Expand All Layers/Collapse All Layers to LayerList widget in Web AppBuilder?

[MattJunker]

There is an Enhanced LayerList widget for the Flex Viewer. Is there a similar Enhanced LayerList widget for Web AppBuilder? My client would like Expand All Layers/Collapse All Layers functionality in a context menu for the LayerList widget, as they did in their old Flex Viewer app. Any solutions or work-arounds for this issue? Thank you.

Hi Matt,

FYI, the ability to expand/collapse all layers will be part of the core Layer List widget in the next Web AppBuilder update in ArcGIS Online (which is planned for this week).

Hope this helps,

Thanks for that note Derek.  I added it to the resource list.  Typically the dev edition follows a few weeks after.  Do you know of an ETA on that?

Thank you Derek!

Will the expand/collapse layers update apply to the Web AppBuilder Developer Edition as well as ArcGIS Online?

Matt,

Yes the WAB Dev comes out a few weeks after the online version.

All,

As Robert Scheitlin, GISP​ noted, the update to Web AppBuilder Developer Edition follows approx. 3-4 weeks after the ArcGIS Online update.

Yes, in the next update.

So when is the next update?

Ana,

   The ability to expand all layers is part of the 2.1 and above WAB just click on the layerList menu button and choose "Expand All Layers". There is yet to be a configuration setting to have all layers expanded by default though.

"There is yet to be a configuration setting to have all layers expanded by default"  This is precisely what we want.  For whatever reason, the average user does not understand they have to click on expand all layers unless they they training.

Ana,

   Well if you are using 2.3 WAB Dev then look at this thread for the code changes to make that happen:
