Multi-select Option Set field - Set a maximum number of choices

(1) ShareShare

Posted on by dynamicallyndsey 10

Hello!

Anyone know if it is possible to enforce a maximum number of choices on multi-select option sets? 

Ideally, we would like a multi-select option set field on a form but only allow a maximum of 2 choice selections.

    Multi-select Option Set field - Set a maximum number of choices
    Hi, The answer on this post is very helpful, but I am also looking to limit it to only two options instead of setting the value to null. Is there a way to deselect the third option and show only two options onColumnChange

    I already tried 

    multiSelect.setValue(selectedOptions.slice[0,2]);

    but the above don't work sometimes, in fact many times.

    Hi Partner,

    You need use js code to enforce a maximum number of choices on multi-select option sets in the form.

    JS:

    function maximumNumber(executionContext) {
        var formContext = executionContext.getFormContext();
        var multiSelect = formContext.getAttribute("new_intendedproductusers");// get multi-select option sets field

        var selectedOptions = multiSelect.getSelectedOption();
        if (selectedOptions != null) {
            if (selectedOptions.length > 2) {
                alert("only allow a maximum of 2 choice selections");
                multiSelect.setValue(null);
            }
        }
    }
