Multiple Select Function in Lists

Currently Ontraport doesn't have an intuitive way of selecting multiple answers in a list. A person has to hold down control to do it (impossible on mobile/tablets) or we have to code in a way to make checkmarks. When we code in those checkmarks (See Video) the form cannot have that question as Required. If that question is marked as required, it doesn't send people to the redirect URL upon form submission. 

So we need an actual fix to the List Selection option where people do not have to hold down control to select multiple items from a list.
