         * @option {Object} [animation] A collection of <b>Animation</b> objects, used to change default animations. A value of false will disable all animations in the widget.
         * <p>Available animations for the <b>ContextMenu</b> are listed below.  Each animation has a reverse options which is used for the <b>close</b> effect by default, but can be over-ridden
         * by setting the <b>close</b> animation.  Each animation also has a direction which can be set off the animation (i.e. <b>slideIn:Down</b>).</p>

         *     <dd>ContextMenu content slides in from the top</dd>

         * _example
         *  $("#menu").kendoContextMenu({
         *      animation: { open: { effects: "fadeIn" } }

         * @option {Animation} [animation.open] The animation that will be used when opening sub menus.
         * @option {Animation} [animation.close] The animation that will be used when closing sub menus.
         * @option {Boolean} [closeOnClick] <true> Specifies that sub menus should close after item selection (provided they won't navigate).
         * _example
         *  $("#menu").kendoContextMenu({
         *      closeOnClick: false
         *  });
         * @option {Number} [hoverDelay] <100> Specifies the delay in ms before the menu is opened/closed - used to avoid accidental closure on leaving.
         * _example
         *  $("#menu").kendoContextMenu({
         *      hoverDelay: 200
         *  });
         * @option {String} [direction] <"default"> Specifies Menu opening direction. Can be "top", "bottom", "left", "right".
         * You can also specify different direction for root and sub menu items, separating them with space. The example below will initialize the root menu to open upwards and
         * its sub menus to the left.
         * _example
         * $("#menu").kendoContextMenu({
         *     direction: "top left"
         * });
