Can lists be nested?

Can lists be nested? I am nesting lists and it doesn't pass validation.

Hello,

I'm trying to get my front page at my web site to validate, and the validator is tossing two of the following errors at me,

Line 60, Column 11: document type does not allow 
element "UL" here; assuming missing "LI" start-tag       <ul>

The only thing that I can think of that might be causing it is that nesting lists in not allowed. Is this a correct assumption?

Thanks, Ray Parrish

What doctype are you using?

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

That's it there. All of my other pages have passed validation. Here are the errors I'm getting -

# Error Line 56, Column 11: document type does not allow element "UL" here;
assuming missing "LI" start-tag.

<ul>

✉
# Error Line 66, Column 13: document type does not allow element "UL" here;
assuming missing "LI" start-tag.

<ul>

And here is my list which is causing the errors

      <ul>

        <ul>
          <li><a href="Hard%20Drives.html">Hard Drives</a></li>

        <li><a href="Video.html">Movies and TV</a> </li>
        <li><a href="Programming.html">Programming</a> </li>
      </ul>

I did just find one <br> tag in the middle of that mess and removed it.

Just glancing through quickly, it appears that you have mismatched tags. See if this helps:

That was it! Thank you very much. It's a little odd to me the way that is done, but now that I know I can nest lists with no problem.
