I have a dropdown that I'm using to filter entries in a Gallery. The user selects a value for the dropdown and then on the next screen the Gallery only shows entries that match the dropdown's value.
Now I want to make it so that the Gallery is only filtered on the dropdown value when the user selects a value from the dropdown. As you know, the dropdown default value is set to the very first item in the dropdown, so even if the user doesn't interact with the dropdown, the Gallery will still filter on that first item that is the default dropdown value.
Is there some other way to implement this scenario? How else can I get the Gallery to filter based on dropdown value ONLY when the user actually selects a value from the dropdown?
