Hi there,

I am quite new to Outsystems and have been working on my first webform. (Attached is only a part of the form). I want to create two dependent dropdown menus where the second refreshes when I make a change in the first one. After searching through the forum and trying different suggestions such as assignments, refresh data etc., unfortunately, I am still not able to figure out how to trigger the referesh in the second dropdown menu. I believe the issue is somewhere with the assignments of variables.

Your help would be highly appreciated.

Thank you



Hi Brannif,

Look into the OML that I published. 

You were near to achieve you goal. You just needed to change something in your filter and in the OnChange action.
