I am having issues duplicate this. I am using this code:
<script>
jQuery(document).ready(function ($) {
$('.iphorm_3_31').change(function () {
if ($(this).val() === '') {
$('.iphorm-submit-wrap-1').hide();
} else {
$('.iphorm-submit-wrap-1').show();
}
}).change();
});
</script>
iphorm_3_31 is my drop down…
