How to make the sidebar collapsable/accordion/dropdown style?

I am currently using the Enfold theme to make my website.

Some of the sidebars have a lot of links and sub-links. This is making so of the sidebars rather huge.

I cant seem to make the sidebar to be collapsible or accordion style or drop-down style.

Basically I need to have a few main menu points always visible and the rest of the submenus to show either on mouseover or onclick.

Is there a way to do this with enfold?

Also the the submenu points are hard to differentiate from the main menu items, is it possible to make the indent and small dot larger?

Thank you in advanced.
