Profile dropdown menu

Hello. I would like to know if someone could point me to the right way in this matter.

The thing is that I need to create a menu just like the dropdown menu in the profile, the one that have the toggle arrows and effect, icons left to the title etc. Where can I find some tutorial that explains how to do that kind of menu?

I investigated how the wordpress profile page do that menu and of course it is done with css, images and jquery, really nicely done! I tried to put something together on my own taking the source code but I failed badly.

Any help will be greatly appreciated.
Have a good week!
