Limit number of checks in multi checkbox

Is there a way to limit the number of checks a person can select in the multicheckbox in the profile/fields?

No.

Kyle,

just thinking out loud here...

I know there is no specific feature to limit the number of selected items in a multi-select field.

Couldn't a CB Auto Action be devised to reject the save of such a field update if the number of items selected is more than a prespecified limit?

Yes - but my question is what would the conditional be?

Items are saved in the database like this:
item 1 |*| item2 |*| etc.

How do count the items?

No, the conditionals can't parse out the value into an array, count it, then redirect away or anything of the sort. It maybe possible with a PHP action so PHP functions can be applied to the POST value using the before profile update trigger and trying to set a user error so it errors the update. However, the problem with all of this is it's after post.. users won't know the limit dynamically and they'll get slammed with an error suddenly after trying to update, which is discouraging to users.
