Hi,
Please check the following topic – there is a short sample code that will allow you to achieve what you would like:

In addition you may try setting the hideTimeout option to some big value to prevent reseting the sub menus on hover out – e.g.:
hideTimeout: 86400000 // one day
Let me know if you have any troubles.
