Hi I have a nav bar for my flash site, which looks like the image attached, on the image there are bars under the text, however I want the bars to appear when i rollover a menu option, so when i rollover history the single bar will slide up from behing the blue box, how can achieve this effect, and make it smooth so it slides in and slides away on roll out? Also with this effect if u run accross all the menu buttons the bars shud slide up and down so to produce a nice consistant flow, can this be done hope somone can help, thanx
