Limit Navigation by Bounding Box Extents

[Todd]

Hi,

I have custom bounding box (bbox) extent polygons which define certain project areas. Each project area has the same basemap datasets, but different project data. I want to design an Experience Builder template (ArcGIS Enterprise 11.3) which includes the basemap datasets and one with the bbox polygons. Intent is to prevent the user from panning outside of their respective project bbox.

How can I use these bbox polygons within Experience Builder to keep a user from panning outside the bbox extents?

Thx,
Todd

I know it's in the plan to add extent limits, probably through an update to the Map Viewer, but it is not currently available.

It's worth mentioning there are multiple threads on this very topic: 
Limit the extent of a webmap - Esri Community (2025 AGOL)

And that this function was available in 2013 WebApp Builder.

Workarounds range from server-object interceptors for filtering,

to custom ExB Widgets,

From that last link, I might try Map frame constraints—ArcGIS Pro | Documentation, but I'd also like to see a configurable navigational extent setting in Map Viewer or Experience Builder, preferably before WebApp is fully retired...
