Question

I have the jQuery UI sorting functionality working fine, but I would also like to add in a basic click action to cause the draggable items to change <ul>. I have the <div class="click_area"> disabled from dragging. What I would like is in the first <ul> if the click_area is clicked then the sortable <li> would move to the second <ul> just as if I had dragged it over. Same deal if the click_area is clicked in the second <ul> it will be moved to the first <ul>. I have created a JS Fiddle for testing: http://jsfiddle.net/helpinspireme/wMnsa/

Any suggestions would be greatly appreciated. Thanks.

$("#unassigned_list, #recipients_list").sortable({
    connectWith: ".connected_sortable",
    items: "li",
    handle: ".draggable_area",
    stop: function(event, ui) {
        updateLi(ui.item);
    }
}).disableSelection().on("click", ".click_area", function() {
    // First figure out which list the clicked element is NOT in...
    var otherUL = $("#unassigned_list, #recipients_list").not($(this).closest("ul"));
    var li = $(this).closest("li");

    // Move the li to the other list. prependTo() can also be used instead of appendTo().
    li.detach().appendTo(otherUL);

    // Finally, switch the class on the li, and change the arrow's direction.
    updateLi(li);
});

function updateLi(li) {
    var clickArea = li.find(".click_area");
    if (li.closest("ul").is("#recipients_list")) {
        li.removeClass("ui-state-default").addClass("ui-state-highlight");
        clickArea.html('←');
    } else {
        li.removeClass("ui-state-highlight").addClass("ui-state-default");
        clickArea.html('→');
    }    
}
