Hi @Corissandageri ,
Do you want the combo box only display the items filtered by the drop down?
If so, Please set the combo box's Items:
Filter(Table1,Supplier=Dropdown_Sup_3.Selected.Result)
Other formulas do not need to modify.
If you want the combo box display items without duplicate value, try this:
Distinct(Filter(Table1,Supplier=Dropdown_Sup_3.Selected.Result),Distinct).Result
In this situation, the DisplayFields and Search Fields could only set to the column.
DisplayFields
["Result"]
Search Fields
["Result"]
The gallery's Items:
If(IsEmpty(ComboBox1Custom.SelectedItems) ,Table1 , Filter(Table1,Description02 in ComboBox1Custom.SelectedItems.Result && Supplier in Dropdown_Sup_3.Selected.Result))
Best regards,
