Convert UL LI into accordion without using jquery

Question

I want to convert a UL LI structure into accordion but without using Jquery.

I am using Angular JS, that's why I don't want to use Jquery and no Bootsrap either as I have my data which gets displayed in UL LI structure only. Please help me convert UL LI to accordion.
