I am writing a webpage that allows the user to navigate among categories and sub-categories of information. It consists of the following items:
1. Left side navigation (a tree-like view of the categories) 3. Top nav bar, which starts to the right of the left nav, consisting of set of top-level categories that act as drop-downs when you hover over them, allowing you to select categories within each top-level category, and sub-categories within those, etc.
This done with a series of nested <ul> and <li> elements, styled with CSS to behave the way I want. The only problem is that if the browser is narrower than the width of the left + top nav bars, the top bar moves down to the bottom of the window (below the left nav), with the actual content pushed down even further.
This problem occurs only in Internet Explorer. In Firefox, the top nav just extends off the right edge of the window, which I consider more appropriate.
