123ContactForm how to set maximum number of choices for checkbox fields

Yes, you can. In your Form Editor, click on the Multiple Choice field in your main view to open its Edit Field panel. Click on the link Advanced. A new subsection will open up, where you’ll see the option Maximum number of choices. Type in the box the maximum number of choices form users can make and you’re good to go.

You can specify in the Field Instructions of the Multiple Choice field that only a certain number of options can be picked, in order to keep things clear for form users. When the users try to select one more option, after they have reached the maximum number allowed, they will get an alert message.
