if you mean a drop down take a look here

otherwise not sure. could you give an example?

That is a great reference.

I want to wade in here though.

There have been a lot of requests (publicly and privately) on having the auto nav having the ability of having a horizontal option along with a vertical option. I know there is an accordion block for drop downs (vertical) but there isn't an easy way in the default auto-nav to have dropdown's much less a vertical option with expansion.

So I asked in the IRC channel about this (the fun one) and apparently there is a bug report submitted for this very thing (allowing drop downs from horizontal only atm) with a few tweaks of the block. Don't know the status of the report atm but hopefully an answer will be coming forth with.

So in the interim, auto-nav templates are the way to go.

Hi, thnx for the link.
I mean just to arrange the page list in the AutoNav horizontally, by default is vertically arranged.
A good example is the AutoNav menu of the Unbound thame
