Is there a way for a drop down list to open automatically using an anchor point?

In case it matters, I’m using WordPress as my website tool.

Basically this is what I have

<a name="title"></a>[expand title="title" trigclass=noarrow] Various text [/expand]

The anchor point is linked from a menu. Is there something I can add that when the anchor point is clicked, the drop down menu opens up? Either that, or is there another way for this to happen?

I’m very new to programming and I’ve tried looking on google but to no avail.

I’d appreciate any and all help!

Thanks!
