Hi All,
I have a Power App screen where I have multiple combo box which are displaying values from a SharePoint List.
From Power App I am saving the selected values in the SharePoint document library basically and they are getting saved using flow.
Now the requirement is, I have a Edit screen as well for the same. When I am selecting a document from Gallery I want to Navigate to Edit Screen and all the field should show the selected item which are basically saved in the SharePoint document library and that is a lookup column in SharePoint with multiple selection.
I am not able to figure out how to show these value in Combo box so that user can see the previous selected values on it and as it is a Edit screen user can change those and again click on Save button so that it will updated with the new selected values.
I hope I was able to clear my requirement. If any doubt please let me know I will try to clear it.
Consider this screen, I have a view icon on click of which I will navigate to Edit Screen

Here is the reference for the same: Yellow highlighted are the combo boxes they need to have values appearing from list.
I have tried to create a Context during Navigation, Label are working but not sure how combo box should work.

Kindly assist, your help will be much appreciated!!
