Hi
is possibile to show a field only if a precedent dropdown menu is selected?
In wpform there is conditional logic with the trigger (is not blank)
The conditional rules for dropdown and other choice-based field types include an option “Empty (no choices selected).” So, if you want to show a field only when a selection is made in a dropdown, you can use the logic SHOW if ALL [field] is NOT Empty (no choices selected). (example)
