I’m using a select tag in a form I’m making that allows multiple selections, but I want to make the maximum amount of selections upto 10. Is this possible using javascript or jquery?

Thanks in advance!

    Here is some full code for you to use…gotta love the Google AJAX API Playground 🙂

    Edit 1: Note: this only lets you choose 5 because I didn’t feel like copy/pasting another 10 options 🙂
