There are two ways to make a transparent gif - first a .gif with its
background the same colour as the page background, though this is not
transparent, and second a truly transparent .gif.
It could be that in FP Design view you are seeing the layer obscuring
the page behind it, rather than the .gif itself. If this is not the
case, then use the image at
www.rxs-enterprises.org/images/tp.gif
1) You have an Absolutely positioned Div located in a table cell.
This is not a good idea, since different browsers will render this in
different ways - the div may move in different browsers. Different
browser sizes may also affect the positioning.
In general, absolutely positioned layers should be directly after the
<body> tag, or directly before the </body> tag - but not in other
containers like table cells.
You can see how I got round this at
www.rxs-enterprises.org/ for
modern browsers, but the method fails in Netscape 4 (and may fail in
other browsers I have not checked).
Using shared borders makes life difficult when also using absolute
positioning - consider replacing your borders with include files, or
even better use a Dynamic Web Template.
2) Do not use the Property-Restore behaviour to close the drop-down
layer - explicitly use a change property behaviour to hide it.
3) You are attempting to hide the drop down layer (see 2 above)
onmouseout from the cell that opens the layer. This makes it
impossible to select any links from that layer with the mouse (and
also seems to throw a JavaScript error).
4) You do not need onload events anywhere in the page, except in the
<body> tag.
In particular, the onload event in the "hide" layer is not necessary.
5) The change property behaviours in the Products layer should be
removed.
6) There should be a behaviour applied to the "hide" image that hides
the products leaf, then another to hide the "hide" layer. Instead
you have behaviours that show the (already visible) "hide" layer, and
the main menu - which never gets hidden anyway.
My menu at
www.rxs-enterprises.org/_borders/globalnav.htm is loosely
based on Jim Buyen's tutorial. However the code has been considerably
tweaked so trying to follow it may confuse rather than help. Also
look at Jon Spivey's menu at
http://myweb.tiscali.co.uk/jonspivey/menus/index.html , which is
easier to implement.
