How to filter a data from Dropdown "B" using Dropdown "A"?

    Hello, I have a question... 

    How do I make it so that when I select a state from my ''State'' Dropdown, it can show only the cities related to the State I have chosen in the ''Cities'' Dropdown?

    Do I need to create an action in the On Change Event of the ''State'' Dropdown?

    If need..., I would like to know what the options are... I would like to know your advice...

Hey  Tatsuya Watanabe, You should bind your entities with static entities which you have made. If this doesn't work. Then I'll share the demo OML with you.
