One way I can think to do this is make your own "menu" tabbed bar in an
image editor. One image for each of the "active" tabs - being the active
page.
You could somehow create a rollover for each if you wished.
Also (as you don't mention the FP version you're using), I will mention that
FP2003 has interactive buttons; one of the designs is a 'tab' design. You
might investigate that.
Alternatively, if you don't want to deal with bulky images, try Google
search : "DHTML tab bar menu" or "javascript tab bar menu" or "tab bar
navigation".
I found a couple of examples:
1)
http://www.asp101.com/articles/prabhu/tabnavbar/default.asp (this may be
too advanced if you're a newbie)
2)
http://www.dhtmlgoodies.com/index.html?page=menuScripts uses javascripts
and the demo is here
Demo of (2) above:
http://www.dhtmlgoodies.com/scripts/dhtmlgoodies-tabmenu/dhtmlgoodies-tabmenu.html
(seems more like what you want?).
You will need to use something like the above as FP has no inbuilt feature
to complish what you're after.
I see the style you looking for on yahoo.com, but I don't know if the above
will accomplish *exactly* what you want or not.
Good luck.
