FROM and TO Placeholders in JQuery UI : Sortable

I am trying to make the list items (cards) sortable, but for usability improvements I want to show the user an placeholder on the old (with text "FROM") and one on the new (with text "TO") before user releases mouse (ends .sortable).

helper: 'clone',
placeholder: {
    element: function(currentItem) {
        retu $('<li class="placeholder">FROM or TO</li>')[0];
    },
    update: function(container, p) {
        retu;
    },
}

right above, you see what I have for now, but is it possible to split "FROM" and "TO"?

Thank you very much <3 Best regards, Patrick
