Hi,
You can use something like this to hide the empty fields in your current tab:
jQuery.each(spjs.dffs.data.tabConfigObj[spjs.dffs.data.selectedTab].fields,function(i,id){
if(id.indexOf("dffsHeading_") < 0 && id.indexOf("dffsHTML_") < 0 && id.indexOf("dffsRow_") < 0){
var tr = jQuery("#dffs_" + id);
if(tr.hasClass("dffs-readonly") && getFieldValue(id).length === 0){
tr.hide();
}
}
});
