Hello,
I have a site form with 2 multiple list fields where values are exactly the same (such as : word=001, word2=002, etc...)
The field multiple list A is visible for visitor. The field multiple list B is hidden for the visitor.
I would like that, when visitor selects one or many values in the list A, the same values are selected identically in the list B in admin form.
How could I do this please ?
thanks for your answer !
