ikiwiki/doc/bugs/maps_with_nested_directories_sometimes_make_ugly_lists.mdwn

I'm using the [[map_directive|ikiwiki/directive/map]] to build dynamic navigation menus, and it's working really nicely!

However on some pages, each nested item each get wrapped in a full set of `<ul>` tags.  This doesn't actually hurt anything, but it's does it inconsistently which seems like a bug.  I don't like it because it puts extra vertical spacing into my menu bar.

Here's what I expect it to look like:

    <div class="map">
    <ul> 
        <li><span class="selflink">Archives</span>
            <ul>
                <li><a href="./2010/" class="mapitem">2010</a></li>
                <li><a href="./2011/" class="mapitem">2011</a></li>
            </ul>
        </li>
    </ul>
    </div>

And here's what it's actually doing:

    <div class="map">
    <ul> 
        <li><span class="selflink">Archives</span>
            <ul>
                <li><a href="./2010/" class="mapitem">2010</a></li>
            </ul>
            <ul>
                <li><a href="./2011/" class="mapitem">2011</a></li>
            </ul>
        </li>
    </ul>
    </div>

I've tried to replicate the problem on this site and cannot, I'm not sure if that's because of exactly how I'm using map or if there's something different with my site.  I just upgraded ikiwiki to the latest Debian unstable as well as most of the required Perl modules and nothing changed.  

If you look at [this page on my site](http://adam.shand.net/ikidev/archives/) (getsource is enabled) you can see it working as expected in the main page and not working in the side bar. 

But it also doesn't work on the sitemap page: <http://adam.shand.net/ikidev/site/map/>

This might be really simple, but I've been staring at it too long and it only looks like a bug to me. :-(   Any suggestions would be gratefully accepted. -- [[AdamShand]]

> Okay, I think I've figured this out, it looks like ikiwiki behaves differently depending on the level of heirarchy.  I'll post the details once I'm sure.  -- [[AdamShand]]

>>> Wonderful, thank you very much for the help!  I've installed the patch and it's working great, but it looks like there a minor bug.  Sometimes it doesn't print the top/first map item.  Cheers, -- [[AdamShand]]
