I have just created a mega menu with two columns, however the menu is opened it is partly off the left hand side of the screen, despite the fact that the screen width is more than adequate for a menu with 3 or 4 columns. There doesn’t seem to be much in the way of options to customise the mega menu either – the instructions just say how to create one in the menu editor. Please can you advise how the alignment can be corrected and what customisation is available for the mega menu?
