Hey.
I have an idea for a flash site I am making, but being new it’s obviously causing me problems! Please see nav.jpg - these 4 squares are going to be nav buttons (each one is an individual movie). What I want to happen is on click of a box (for example the third one along) a box of the same colour appears underneath it (nav1.jpg), this is where all the info of the category willl go.
Prferably I would want the box to slide down from the nav buttons to appear there rather than it just appear from nowhere, but if this is difficult then fair enough.
I’m also interested in changing the opacity of the nav buttons on mouseover?
Can anyone help me or know a site that could? I’ve searched around Kirupa but couldn’t find alot on this subject.
Thanks alot, and please remember I am new!
