Answer 1

You have to do a new CSS-Style for .nav .subs ul for the whole block or .nav .subs ul li for a single element of the block
example:
.nav .subs li ul
{
max-height: 0;
-moz-transition:1.5s;
-o-transition:1.5s;
-webkit-transition:1.5s;
transition:1.5s;
}
.nav .subs li:hover > ul
{
max-height: 300px;
height: auto;
}
.nav .subs li ul
{
left: 250px;
top: 0;
overflow: hidden;
}
this just shows the new block, if you hover over a submenu-item, now you only have to style it and place it whereever you want it
