    How can I make it so once an option is selected (from checkbox) others filling out the form cannot select it?

    I am looking to make a form for people to signup to volunteer. Once we have a position filled, we don't need it anymore. How can I make it so each option can only be selected once?

    Hello bknis,

    Yes it is possible to achieve your requirement. 

    You may like to take a look at out "Gift Registry" widget which should help you. This will ensure that once a position is selected, it will not be allowed to be selected again by other users.

    Another option is to make your question a "Unique Question" but it will not work in your case as the check box question cannot be set as unique question.

    Hope this helps.

    Do get back to us if you have any questions.

    Thank you!
