Hi all, i've been searching for a formula to filter a dropdown field using a search bar (text input) filed.
The used case is: I have two SPO lists one is called Suppliers and another Materials.
Every material has a supplier attached to it (like Apple - Iphone, Windows - Surface, etc.)
In my PA this are two separate dropdown pointing to it's respective list.

dpdSupplier - Suppliers.Title
dpdProduct - Suppliers.Title
searchSupplier
searchMaterial
Connection in SPO is that Products has a lookup to Supplier
Supplier is a standalone list

I'm trying to filter only the dropdown options based on the search box text by Product/Supplier title
Thank you for the help, and regards.
