Power APP-cascade drop-down from lookup list showing just 1 Item

I have a Contract Sharepoint List (Main List) which has multiples columns, the importances ones are Group Owner and Email Address Owner, both are Lookup Columns for a secondary list (Owner List) and i have a third List named Groups with a single line text column where i upload all the groups.


* Group Owner - "Grupos" on the secondary List - Lookup column, data is coming from the third List.

* Email Address Owner - "Email" on the secondary List- Single Line Text


Now I have created power app form on the Main List, if a user selects any Group Owner corresponding emails should be load in Email Owner column so user can select any of the emails (if there are multiple for that group).


I tried multiples workarounds to make this work, however the closer aproach just it is showing me 1 item.




Filter('Owner List', ID = cbGroup.Selected.Id)







Hi @Ranp34 


Do you want the Owner Email combo box items depend on the selected Group in Group Owner combo box?


If you do, please follow the two steps below:


1\ Set the Group Owner combo box Items property to:



2\ Set the Owner Email combo box Items property to:

Filter(Owner, Group.Value = cbGroup.Selected.Value)   // or Id instead of Value if you look up Id of Groups


Hope this helps.

An Update, the combox works great on the Powerapp Panel.


However, when I saved the record, it refuses to save the field. All other fields are saved correctly. So, that field stay empty on the list.


Someone could help me?
