Same secondary menu bar on different pages and lead to different content
If you are just using hashes to flip between hidden divs on the page, then the submenu needs to just be relative to the current location like | &lt;a href='#sales'&gt;sales&lt;/a&gt; | and your main menu would just have the paths to the nodes like | &lt;a href='product-a'&gt;PRODUCT A&lt;/a&gt; |

This might seem like a pointless answer, but if my assumption about you using the hashes to switch the tabs, then the solution is super simple. You just need to create the submenu in code in the template since the admin-based custom menu system won't let you do relative hashes (I don't think so anyway)
