Drop down menu items work well on desktop, but not working on mobile. Sub menus don’t work

I am trying out this theme and it’s looking like the pictured layout with the slider next to the category/sidebar is only available in the pro version. How do I achieve this in the free version? If Pro is the only way you should change the photo.

The slider of ecommerce lite theme is not responsive. Can anyone tell me how to make it responsive.

how can we change home page demo content?
