                <p><span class="initial-space"></span>In this sample you can drag drop items within the same TreeView or from left TreeView to the right TreeView and vice versa. When item is dragged a drop marker is displayed showing the exact location at which dragged item can drop. If the marker is not shown, the drop position is not allowed.</p>
                <p><span class="initial-space"></span>You can reorder items by click and drag over specific item. A dragging window will appear, stating the target item and position at which item can be dropped. During drag drop operations, you can also create a copy of an item by holding the SHIFT key. The dragging window will change its icon, showing a <span style="color:#c60d0d;font-weight:bold">+</span> sign next to the position marker.</p>
                <p><span class="initial-space"></span>While dragging an item over middle space of some target item, when dropped the item will be added as a child of the target item. If the <span style="color:#c60d0d">autoExpand</span> property is set to true, the target item will expand, after a short delay of 500ms.</p>
                <p><span class="initial-space"></span>By clicking on check boxes, you can change the built-in properties:</p>
                <ul class="feature-points">
                    <li><span style="color:#c60d0d">allowDrag</span> - determines whether items can be dragged</li>
