Adding some code in the menu

Hi all, I have a menu system that is set up so that my Links are like so.

<ul>
<li><a href="#nogo"><b>Nav Links</b></a></li>
</ul>

HI can get the nav links to work properly by using this code.

<ul>
<li><a href="<?php bloginfo('url'); ?>/"><b>Home</b></a></li>
<?php        wp_list_pages('title_li=');       ?>
</ul>

My problem is that I can’t add the b Tags in the nav.

Note: The reason I’m using the b tags isn’t for styling, it’s for functionality of the dropdown.

Any help with this would be awesome, thanks.
