Collapsable Headings

Like in back of house where you can collapse the sections in your menu, if you could have this feature for the customer side, this would make the menu easier to navigate for the customer, especially if each header could have a photo. For example:
Fish Dishes
Steaks
Alcohol
Desserts
Then have them open up to display the choices in that category. Our menu currently involves a lot of scrolling by customers to accommodate our products.
