[html-formfu] set multiple values to hidden element?

[Hu Hailin]

Hi,

Let me try to make an example:

a employee search page and can be searched by department.
Suppose there are hundreds of departments, showing a very long
multiple selectable select element seems not a good idea.
I try to make the page only take departments' id from query and
display the departments' info in the page.

Even if use a block element, hundreds of departments info have to be
listed in page, right?

Well, it seems I have to serialize data...

Thank you, guys.
