Dropdown menu workarounds

[ConservationPlanner]

I am building an app in experience builder which has a Map Layers widget with a corresponding webmap. The layers are organized into groups where there is one particular group (called Themes) that has three possible subgroups of layers only one of which I'd like to be turned on at a time. I can achieve this with radio buttons by making the Themes subgroups exclusive in the web map, but I'd like that particular dropdown to appear expanded when the app is loaded, so users can see the options for themes right away rather than having to open up the Themes group. I don't see that there is a way to do this. Is there some other widget I could use to simulate that experience? After some searching I see that there isn't a dropdown widget that I can use directly.

Hi @ConservationPlanner ,

Could you try the Accordion widget? 

To achieve a better effect, please follow the steps below:

1. In the Accordion widget settings, select the desired widget in "Expand items on loading"

2. Set both the Accordion widget and the inner widgets to Auto height
