Hello, I have 2 SharePoint lists with "Choice" type columns that look like this :

I would like to create "Cascading Dropdown" on a form with Power Apps, by connecting to my SharePoint lists. But I don't understand at all how to do this with choice type columns. Everything I try fails. 😞

For example, I tried to write this:

But when I launch my Power Apps form, it doesn't work, the items of "Filiere" are empty :

Can you help me please ? Thanks in advance ><

Hi @s44 ,

Distinct( AddColumns( Filter( 'Categorie et Filiere'; Categorie.Value = DataCardValue2.Selected.Value ), "FiliereValue", Filiere.Value ), FiliereValue ).Result

What Shane Young does in his video doesn't work. Because I have ComboBoxes and not DropDowns @Pavan_Mani_Deep

Indeed the video does not offer any solution to solve your problem. But I'm just as stuck as you. It's a very strange problem.

@s44 ,

How many items are in the list 'Categorie et Filiere' ? The Distinct filter is not Delegable

The syntax is valid - I just did a test here to confirm this as below - Items of the second combo box

I'm sure, but here "Source de données" is grayed out. Maybe that's the problem? @WarrenBelz
