I want to create this menu where on hover a dropdown menu appears and normally I would have no trouble doing this setting the UL to top:100%. However this time I need it to be further down but it needs to be precised so it is cross browser friendly. So what I tried is to set a margin-top:17px to the UL container to push it away from the top and that works but as soon as I hover over it, the dropdown closes. I added a RED border in the example to show where I would like the dropdown UL top to start.
Please have a look -> Link to example
