Share point List - Parameter Forms empty (no choice)

Mansuy Frederic - Epta France 1 Reputation point

I created a SP list from Excel.
When I go into the parameters of this list, the Forms parameters is empty. I can't choose the kind of forms. My goal is to have the possibility to modify the form of the list.
And when I display my list, in the menu barre, there is no 'integer' menu which allow to have 'powerpass > modify form'.

It is strange. If I create a list directly (from nothing), I have these menu and the possibility to modify the form.

Do you know how to activate this possiblity for my List created from Excel ?

Thank you

    Hi @Mansuy Frederic - Epta France ,

    Can you try to just create a new Canvas App and "Start From Blank" in PowerApps? Then go and add your Edit Form on any empty screen, hook it to that SharePoint List, and you should be able to accomplish the goal that way.

    If the option "Customize Forms" is missing from just one list, there may be a column with data type in that list it doesn't support for that feature. So that may be why it shows on one but not the other. And also you could try carefully cloning the list and slowly removing columns one by one and see which one(s) it is.

    However other than that we don't think this precludes you from using this List in a PowerApps Canvas App. You could alternatively just select "Create an app" (the very first option) and see if that helps instead, as that may still generate the app with the form on it. If you go the other way and use "Create App" then "Import Spreadsheet", you will be able to make a customized Power Apps form (the option will become available).

    Also, for explanation of your question why "Customize forms" is missing check the below:


    • If the Customize forms option isn't available or doesn't work correctly for your list, it might contain data types that Power Apps doesn't support. Also, you can't move your form to a different list or environment.
    • Custom forms for lists are only supported in generic lists and generic document libraries. List and library templates are currently not supported; including but not limited to lists such as Announcements, Contacts and Tasks.
