## An optional model-to-javascript tree renderer for mongoid_nested_set

Can be used to turn association select to a tree select, like this:



    #checkboxes
        -# with simple_form
        = f.association :categories, as: :check_boxes, collection: Category.all

        -# with formtastic
        = f.input :categories, as: :check_boxes, collection: Category.all

        -# without any
        - Category.each do |c|
          = check_box_tag "item[category_ids][]", c.id, @item.category_ids.include?(c.id)

    #tree.controls.input{style: 'width: 220px;'}

    :javascript
        var categories = #{Dynatree::Renderer.new(Category.nested_set.all, f.object.categories).render()};
        $(function(){
            $('#checkboxes').hide();

            $("#tree").dynatree({
                checkbox: true,
                selectMode: 3,
                classNames: {
                    active: "dynatree-active-no"
                },
                children: categories
            });

            $("form").submit(function() {
                var tree = $("#tree").dynatree("getTree"),
                    arr = tree.serializeArray(),
                    sel = $('#checkboxes');
                sel.find(':checked').prop('checked', false);
                $.each(arr, function(k, v) {
                    sel.find('[value=' + v.value + ']').prop('checked', true);
                });
            });
        });
