How do I put a limit on my order form?

I have created an order form, and in the checkbox section, I want to make sure people can only pick up to 3 options. How do i do this please?

Thanks!

It is not possible to set the limit on the payment integration settings, but it is possible to count the number of selected items and show a message indicating when more than 3 have been selected, you could also hide the submit button so the user does not submit the form.

Once added you will need to add the count() function and include the payment integration:
