This is actually not up to par with how it should be done. There is actually a template hook for the search dropdown that vBulletin Developers placed in to be used by their products such as the blog and project tools. Which if it was setup properly you wouldnt have to change anything for it to show up on vbadvanced or anything other high customized addon such as the arcade which it doesnt show up on.

I created a few of these addons on my site and have a few more planned. Maybe I will package my code up into one proper package for release so you can add in search for tags, members, social groups, arcade(if you have it installed), and maybe a few others.
