Hi @liingy ,
Try This
To display specific choices in the second dropdown based on multiple selections from the first dropdown in PowerApps, use the Filter and Collect functions:
ClearCollect(
NextDropdownOptions,
If("Choice 1" in Dropdown1.SelectedItems.Value, Collect(NextDropdownOptions, Filter(Choices, Condition1))),
If("Choice 2" in Dropdown1.SelectedItems.Value, Collect(NextDropdownOptions, Filter(Choices, Condition2))),
If("Choice 3" in Dropdown1.SelectedItems.Value, Collect(NextDropdownOptions, Filter(Choices, Condition3)))
// ...repeat for other choices
);
// Set the Items property of the second dropdown to:
Dropdown2.Items = NextDropdownOptions
Replace Dropdown1, Dropdown2, Choices, and Condition1, Condition2, Condition3 with your specific control names and conditions.
