How to create an inset map independent of main map frame

[Cheriejn]

Hi! I have been trying to create a map in arc gis pro and I want to add an inset map with extent indicators only. Every time I try to add a new map frame it automatically includes all the layers open on my main map frame. I can add the extent indicator just fine, but I can't figure out how to remove the layers on the inset map without removing them on the main map.  I am not sure what I've been doing wrong and could really use some advice. I haven't been able to find anything online that has helped. >_<

Both map layouts and layers of each map are listed in the table of contents (left hand pane) right? Can you just expand the mapframe dropdown in the TOC right-click and remove them?

Hi David! When I expand the mapframe dropdown menu and deselect the layers or attempt to remove them it removes those layers on both mapframes.

Ah yes sorry, I think if you create a 'New Map' (top left corner for me), then insert that new map into the layout it will then stop being linked.

Yes that was it!  I needed to create a new blank map and use that as my map frame for my inset map. I thought using the default map would have allowed my to edit it separately from my main map, but that wasn't working. 🙂 thank you!
