Filtering repeater with dropdowns

Hello, I know there are already multiple discussion around this natter but I do not manage to set up the repeater filters with dropdowns properly.

What I am trying to do:

  • 2 dropdowns to filter the repeater. The dropdown “Brand” must be use first in order to enable the 2nd dropdown “Modele” (This function is not includes in the codes below as I do not know how to do it)

  • Each dropdown must includes “All Types”, it works!! However, the data does not appear in the 1st dropdown. I only have “All Brands” in the 1st dropdown (#dropdown2 / data “brand_name”)

  • The purpose of the 2nd dropdown (#dropdown3 / data “model_number”) is to filter data from the 1st dropdown. Example: if I select “Apple” in the 1st dropdown → I just want to have “Apple products” on the 2nd dropdown. Today, my 2nd dropdown does not take into account the 1st dropdown selection. How to make it happen?

  • Repeater are connected to the dataset “(#dataset1)”

  • Collection name is ("MobileFR)
    Thanks for your help !!!
