Field 'other' in dropdown menu with free text field

[Jeroen6]

I've made a category item with on it a form with a drop down menu. The last option of the drop down is Other. When selecting that, there should appear a free text field. How do I do that?

Hi @Jeroen 

It should be simple UI Policy

1. Create Text field

2. Write UI policy with Condition if category is Other then Show text field. Mark Revsere if false true.

Thank you
