Begin by placing the markup for the two-column Grid on the page (this example uses the Grids Preset Template 1, 160px left). Next add the Menu markup for the root Menu instance to the left column of the grid.
method of the Event utility to instantiate the Menu as soon as
its markup is available for scripting.
This Menu instance makes use of several configuration properties. Setting the "autosubmenudisplay" configuration property to "true" modifies its default behavior so that mousing over any item in the Menu automatically triggers the display of its submenu. The "hidedelay" configuration property is set to "750" so each submenu automatically hides 750ms after the user's mouse has left the menu. The "lazyload" property is set to "true" to help speed up the initial load time of the Menu instance by deferring the initialization and rendering of each submenu until just before it is initially made visible. Lastly, the effect configuration property is set to use the pre-canned FADE ContainerEffect instance bundled with the Container Core package to animate each submenu's opacity as it is shown and hidden.
Submenus are added to each item in the Menu by subscribing to the "beforeRender" event and setting the "submenu" configuration property of each MenuBarItem instance to an object literal containing the necessary data to create the submenu.
Finally, it is necessary to set the "position" CSS property of the root Menu
instance's element (
<div id="#productsandservices">) to
"static" to match that of the "position" configuration property.
