Hello @mrpetreli,
In this case you will need a little of additional code.
– Insert a “HTML Content” field in the form, with the following piece of code as its content:
<script>
jQuery(document).on('change', '[id*="fieldname1_"]', function(){
if( jQuery(this).val() == 1)
{
jQuery('[id*="fieldname100_"],[id*="fieldname101_"]').addClass('required');
}
else
{
jQuery('[id*="fieldname100_"],[id*="fieldname101_"]').removeClass('required');
}
});
</script>
and that’s all.
Now you simply should edit the previous piece of code to use the real fields’ names and the correct value in the comparison.
Best regards.
