How to Link or add categories to home page menu

Hi friends,

I got stuck on this and asked so many times on live chat but still havent found solution for it..

I added categories through coupon manager (which we can see while adding listings) but i want same categories on home page menu as well …

eg on demo page (https://coupon.wlthemes.com/) there are button on menu like home/blog/storelist/addlisting and i want categories next to it.

so if user post deals through add listings then that while clicking through menu categories “all categories will be displayed”

I did tried to create categories through apperance which helps me to add on post if i post deals but what happen if users post deals so then i got stuck…

please help me out to get this solved……whats the correct way to set this..

I also want categories on right side bar ……so cat on menu , side bar and on while listing …all link to each other for all website..

thanks guys
