The mega-menu is available for use on College sites. It contains several elements that you can customise for your website:
'You are here' highlight
The page that is currently open on the website is indicated on the menu with a white background. If your site has its URL structure and breadcrumbs set up correctly, then the default ACTON theme would take care of the styling.
The old format suggested having a menu area that appears on the left side of each website within a narrow column. For advice regarding that old menu format and the rules associated with that layout, please refer to the relevant page.
