bagheera -
I had seen the limit_choices_to parameter, but I thought it controlled
*which* choices are available to the user - not *how many* they're
allowed to choose.
I want to show the user a list of 20 or 30 cuisines, but forbid them
from checking more than three.
Can you show me an example of how I'd use limit_choices_to to limit
the *number* of choices the user can select?

or u can add a js script to this form field that will disallow selecting
more than three items instead validating model (or do both).
