I have a dropdown menu that works fine, but I would like it so, that if I hover off the menu, it doesn't immediately hide again. So basically I would like a one second delay.

I have read about setTimeout, but not sure if it is what I need?

$('#mainnav a').bind('mouseover', function()
{
    $(this).parents('li').children('ul').show();
});

$('#mainnav a').bind('mouseout', function()
{
    $(this).parents('li').children('ul').hide();
});
