Include "select all" in a scroll down menu in a custom form.

We have custom forms that have scroll dow menus and we like to add the option "select all" in the scroll down menu , similar to scroll down menus in Excel. Is there a way to include this slection in a scroll down menu in a custom form?

Do you mean a check-box dropdown? If so, there is a select all for that type.

Hi, 

Does this still exist? I'm looking at a Dropdown field with the 'Allow more than one option to be selected' option checked, but I don't see a 'Select All' option.

You won’t see ‘select all’ as an option when you’re building the custom form field, it just shows in the live form automatically added.

what I meant to say was to include in the dropdown menu "select all" when applicable

where would be the "select all" chweck-box for a dropdown?
