Limit the extent of a webmap

[Oliver_Burdekin]

Is there a way to limit the extent of a webmap? I have a custom basemap that only cover the area of interest and I would like to prevent the user from panning / zooming around the whole world and keep them within the limit of the basemap.

Hi Oliver,

I don't believe this is possible in the webmap itself but it is a configurable option in some of the Instant Apps applications through a 'Navigation boundary' setting: keeps the area in the map in focus by using a navigation boundary or disabling the ability to scroll.

You can narrow down the options by searching for 'Navigation boundary':

In the app, disable 'Express' mode and the 'Navigation boundary' will be an option through the menu. This is what it looks like in the Basic app:

@CarmelConnolly  is right, the web map spec currently does not have a property to set the max navigational extent.

Thanks @CarmelConnolly that solution would work for a standalone app. As I understand it web apps cannot be added to the new storymaps in sidecar or slideshow mode. I suppose one work around would just be to make the maps non-navigable and embed an app with Naivgation boundary set at the end of the storymap.

Update! Just realised I can "embed" an app in sidecar

Oh interesting, I see that embedding web apps doesn't working using the + option, but have you tried the Add > Embed option? I was able to embed a web app as background app, that was interactive with the navigation boundary.

Hi, when will this function be included in the experience builder UI?
