Services Dropdown

It would be a great idea to have a dropdown feature added, to when people go to the site to book, they don't just see a full list of services, which can seem a bit confusing. E.g. a dropdown for all hair cutting services, and when they click, they can choose what service within that section they wish to book for... 

Just think that it can be a little off putting when going to book, and seeing a long list of services all mixed up, even though there is a title, most people won't look for that, they will look for the easiest option.
