Question about Jevelin theme w/ Fashion demo

I am new to the template and wondered:

  1. How can i add another option to the menu dropdown? Right now I’m able to create another category from the top bar, but wanted to make a third menu selection popup. So WoodTypes —> Softwood —> This would be all softwoods…
  2. I need to change the Fashion items, dresses, pants etc. to my items and i don’t understand where i replace them?
    Thanks in advance
