cascading dropdown set default value blank

[s44]

Hello,
I am creating a Power Apps application with cascading dropdown menus. I'd like these cascading dropdown menus to default to an blank value, but I can't seem to do that.
Could you help me please ? 😞 Thanks in advance !

My app is like this :

For the first dropdown, I have this code : Items =  Sort(Distinct(Categorie;Categorie);Result)

For the second dropdown, I have this code : Items = Distinct(Filter(Filiere;Categorie.Value=Dropdown2.Selected.Result);Title)

For the third dropdown, I have this code : Items = Distinct(Filter('Sous-Filiere';Filiere.Value=Dropdown5.Selected.Result);'Sous-Filiere')

My Sharepoint list for the first dropdown :

My Sharepoint list for the second dropdown :

My Sharepoint list or the third dropdown :

Hi @s44 

Did you already try to make the Default property of all dropdowns blank? This will make the default value of your dropdowns blank.

Hi @s44 ,

Set AllowEmptySelection to true

@s44 ,

Two things - that actually should work (I use it regularly) and secondly, you have the field and list name the same (not a good idea), however another approach is to make a collection

ClearCollect(
   colCategorie;
   {Result: ""};
   Sort(
      Distinct(
         Categorie;
         Categorie
      );
   Result
)

then the Items of your drop-down would be colCategorie

@s44 ,

I can assure you it does - example from one of my lists below.

I think your issue is the identical list and field names.
