How To Filter Form Drop Down That Is A SharePoint List Lookup Column

[BenTalbott]

Scratching my head on this one.....

I have a SharePoint Online list which is my data source.  I am building a canvas PowerApp on top of it.

One of my fields in the SharePoint list is a lookup field, getting information from another SharePoint Online list.

I can display this in its default state in the form no problem.

However, what I need to do is filter the drop down in the form based on a column in the list being looked up.

Main SPO List name - NIR

Main SPO List field in question - PPC

SPO List name being looked up - ItemFamily

SPO List field being displayed - PPCName

SPO List field to filter on - Display      (this is currently a text field, but can be any field type if I can get this working)

So in the form the drop down field currently shows all items in the lookup list.  The fields Items property is;

Choices([@NIR].PPC)

From what I have read, the choices function returns two columns ID & value (in this case PPCName)

Is it possible to filter this Items property so that only records where a 3rd column equals something are shown? (Display = "Yes")

Hi @BenTalbott ,

You can filter the DropDown Field like below - 

Filter(SharePointListName,DropDOwnField.Value="New/Pending")

For this, you will need to get rid of the Choices function in your formula.

You will need to Filter the looked up list directly.

To simulate this, you can use the following formula on the Items property formula of your DropDown:

Filter(
   ItemFamily,
   Display = "Yes"
)

This is assumed that Display is a Text Column in your ItemFamily list.

If you want the EXACT results as the Choice function, you can use the following formula:

RenameColumns(
    ShowColumns(
        Filter(
            ItemFamily,
            Display = "Yes"
        ),
        "ID", "PPCName"
    ),
    "ID", "Id",
    "PPCName", "Value"
)

I hope this is helpful for you.
