Slider & Menu

Hello,
I really enjoy the setup of the Phogra template. I would help me though if I could start with the menu slider on the side open, with the option to close it. Now there is the small trigger in the top-left corner, which is nice, but I’ve had a couple people mention that it is a little confusing for them to understand where to find the menu at first.

Also, I was wondering if the sub-items on the menu bar are supposed to open up below the main ones? Right now I have built the menu where there are general topics with some sub-categories. Does the menu/CSS allow for the menu items to expand?

Any help would be appreciated
