okay, I got it:

Code:

            onDrop: function(target,source,point){
                var idParentCategory;
                if(point == "append") {
                    idParentCategory = $(this).tree('getNode',target).id
                } else {
                    if($(this).tree('getParent',target) === null) {
                        // is root
                        idParentCategory = 0;
                    } else {
                        idParentCategory = $(this).tree('getParent',target).id
                    }
                }
                console.log(idParentCategory)
}

Thank u all

Nobody knows how to? 

Hi,

I'm trying to get the id of the new parent node of the element that has been dropped. The further thing I've got is this:

Code:

onDrop: function(target, source, point) {
    $(this).tree('getNode',target).id;
}

Which gets the ID of the drop target, but not always is the parent, It may be a sibling when it is dropped next to it.

Thanks,
xavi
