Adding Category to Menu Bar

Hi Guys,
Could do with a bit of help. I’m trying to create a menu for a site i’m working on.

A menu item labeled “fruit” would contain links to sub-catergirues named “berries,” “citrus,” “tropical,” etc. I do not want an actual “fruit” page. Is there any way to do this? (taken from a previous post).

Please feel free to take a look at the site. sllet.thewtech.co.uk.
