2 Mandatory Fields in Blocks

Q. Is it possible to have two fields in blocks but one of the blocks is mandatory to fill out?

A. Yes using javascript in the boostrap layout section for the product you can enter the following. substiture phone and mobile for block names.

<script>

    function _initPreview() {

        if ($("[data-blockname='Phone']").val().trim()=="" & $("[data-blockname='Mobile']").val().trim()=="")

        {

            alert ("Phone and Mobile Cannot both be Empty!");

            return false;

        }

        return true;

    }

</script>

For Multipart blocks use something like this:

<script>

    function _initPreview() {
        if ($("[data-blockname='Direct'] input").val().trim()=="" & $("[data-blockname='Office'] input").val().trim()=="")
        {
            alert ("Direct and Office Cannot both be Empty!");
            return false;
        }
        return true;
    }

</script>
