How to add and edit a field in a Form

After the settings options appear, click at ADD AN ELEMENT (Symbol: +) and click at FIELD:

That's it ;)

If you need to edit the name field, just click at EDIT FIELD:

A box will open and you can edit the field name. After you're done, click SAVE.

That's it ;)
