Multi-Level dropdown in Mendix

Hi, Is there any way to have a multi-level dropdown with on-click action as Microflow-call like below image in mendix .     I tried creating the custom widget but mendix is not allowing to pass nested objects to widget in the xml file (where nested object could be the data for multi-level dropdown items) when I try putting object type property inside object its throwing the error like cannot put object inside object.   Thanks, Ibraheem

Hey Ibrahim,

You can follow the link below to create a multi level drop down,

in this answer I have explained how to create it,

and after the implementation is done, you can apply a custom CSS to make it look like the image.

Hope it helps!
