I am intending to use a collapsible menu similar to that used at http://slashdot.org (left side) . I have a problem however :
I want the menu to expand immediately ON PAGE LOAD, without need to click on top bar
The package can be downloaded from http://www.dynamicdrive.com/dynamicinde ... otmenu.zip
-----------------------------------
I have included the script below. CAN SOMEONE HELP AMMEND IT ? :
"
var remember = true; //Remember menu states, and restore them on next visit.
var contractall_default= false; //Should all submenus be contracted by default? (true or false)
var menu, titles, submenus, arrows, bypixels;
var heights = new Array();
var n = navigator.userAgent;
if(/Opera/.test(n)) bypixels = 2;
else if(/Firefox/.test(n)) bypixels = 3;
else if(/MSIE/.test(n)) bypixels = 2;
