android - Getting section headers to work with SuperSLiM and RecyclerView -

currently i'm trying implement section headers in recyclergrid in android. came across superslim has functions need.

now problem is, in opinion, it's badly documented how implement it's working. reading through given example, it's full of functions partly understand do.

my own implementation of superslim worked far showing headers , custom views use items, crazily messed while scrolling. (items shown multiple times, headers went on items , forth)

my simple question is, can provide me simple , understandable example on how implement superslim manager (as grid manager) recyclerview? if there better alternative appreciate help.

if it's not clear on how layout should have example image below:

important mention is, items not simple textviews comparable cardview.

thanks lot in advance!
