I was hoping if someone could do this for me, basically I'd like to have a parentcategory. For example this one:

''Remixes''

And when you click on it a couple subcategories slide down from under it. Like this

''Remixes''

- Acapellas

- Instrumentals

- Requests

I'm willing to pay anyone who can write this for me, shouldn't be to hard right?

Here's my site btw;

It would also be nice if the parentcategories had like a small arrow next to it so people would know that if you click on it subcategories will slide down. 

Thanks in advance!
