Fluid Width On a Block Element Containing A Horizontal List
Question
I have a problem. Working on a php script, I must first get the HTML/CSS down right. My goal is to write a vertical menu, that shows a horizontal list sub menu, containing more vertical menu lists.
The problem I'm having is my horizontal list with my block element will not appear horizontal, not unless I add a fixed width to the block element. Is there a way around that?

If you add a fixed width of about 500px to the .sub-container, then the horizontal list within it works. I cannot add a fixed width because it wouldn't work as intended when I add in my php. I tried using other display values besides block, but none do the trick.
I suppose I could use a table instead of a horizontal list within my display:block element, but I would like to avoid that if possible because it's not really tubular data. EDIT : using a table has the same issue as the horizontal list, so that won't work properly either.
Sorry if i don't make sense, I'm not an expert with proper terminology...
Any ideas?

The reason why the lists are being constrained to that width is because is inheriting the width from #vertimenu and ul.main-links li , which is set to width: 150px; .
Remove those set widths and give ul.main-links li a width of 150px instead.
