Disable an item of drop-down-list from another page.

Disable an item of drop-down-list from another page.

Hi,

I'm still here ...

I would like to know, if is possible, how to disable or to enable a drop-down-list from another page.

I mean: I have a drop-down-list in select.php and I would like to disable or to enable a single item, more than a item or all the items from panel control (control.php) page.

Thanks in advance.
