There is no restriction (see screen shot with 11 items) - it will be off the end of your screen..
As it's an absolute positioned element (<div style="display: none;" class="FlexibleDisplayCartContainerOut">) - it has to be to appear and disappear on the mouse-over without pushing down the lower divs - it is out of the scope of the surrounding container so the browser sees no extra height to make the window scroll..
If it did show then your page would be 4-5000px long.. :( - but it can't..
Perhaps play with the css to give you 3-4 products across? Depends how large each product display is though..
e.g.
add this css to your template?
.FlexibleDisplayCartContainerOut {
min-width: 700px;
}
#FlexibleCartProducts .FlexibleCartProductROW {
float: left;
height: 120px;
width: 300px;
}
gives you on our demo site 2 across (see att. dropcart_11_3.png)
