How I can show or hide fields according to selection of a dropdown field

I need show or hide several field, after select an specific item.

How I can do?

Thanks you very much.

Make sure you add the dropdown menu with all the options, as well as the fields to be shown or hidden.

Then, follow these steps:

Go to “Setup & Embed” and click "Conditions".

Select SHOW/HIDE option

At  IF declaration, you must choose your dropdown menu :

On the THEN declaration, choose the field you wish to show only if that conditon is met (otherwise it will be hidden)
