Thanks for that.
What we've got at the moment is the top bar with 'home page', 'about us', 'how we work', 'estimates', 'work for us' and 'terms and conditions' buttons and on the left we have a number of collapsible menus for various categories of service.
I don't think the top bar is under discussion at the moment. Basically, management is trying to decide whether they want a long list of individual services on the left or to stick to the collapsible category menus as at present.
