[support] make a controlled field independant of the controlling field via form alter

[Benjamin Jacob]

Hi,

I have got a few conditional fields, say B & C controlled by the controlled by A.
Now in some scenarios controlling field A auto selected and hidden (by setting '#type' to 'value') in hook_form_alter.
With this B & C stay hidden too. I don't want this.
I want B & C to be visible and editable by the user even though the controlling field A is hidden.

How do I achieve this?

cheers
