[development] Multiple similar Forms on same page

[Ernst Plüss]

Hi All

I'd like to show the same form multiple times on one page. I tried to
do this by calling drupal_get_form in a loop. Unfortunately this
doesn't work since drupal makes them 100% identical (same form id and
form-token) which means up on submition drupal cannot tell which form
has sent the answer.

Note that the forms are not 100% identical, they differ by things like
item id and selection options. This is handled in the form building
function.

What's the right way of implementing this?

Best Regards
Ernst
