menu types

[supermanjnk]

I'm not sure this is the best place to put this but it didn't seem to fit anywhere else.

What i'm wondering is, right now i have a javascript tree menu, on another site i have a javascript drop down menu using divs, another one my menu is just plain html, I know which one you use has a lot to do with the layout and i know you can't really compare a dropdown with a tree menu (unless you consider a dropdown also a side menu with a div that pops outward)

I also know that it's a matter of preference, but my question is, user friendly wise, it is better to have a dropdown/tree menu, or just list the links like
<a href="/link/page.ext">link</a><br> my other question is with spiderability, is there any penalty for any of these?

Thanks.

Plain html menus are a lot easier to use. You can see what you're looking for, instead of guessing where it might be, or giving up because you didn't realize the menu was interactive. JS menus can be hard to click the right option on, are interfered with by some ad blocking software, and a small percentage of surfers have JS disabled.
