Here's my answer using jQuery:
jQuery.fn.ddnav = function() {
this.wrap("");
this.each(function() {
var sel = document.createElement('select');
jQuery(this).find("li.label, li a").each(function() {
jQuery("<option>").val(this.href ? this.href : '').html(jQuery(this).html()).appendTo(sel);
});
jQuery(this).hide().after(sel);
});
this.parent().find("select").after("<input type=\"button\" value=\"Go\">");
var callback = function(button) {
var url = jQuery(button.target).parent("div").find("select").val();
if(url.length)
window.open(url, "_self")
};
this.parent().find("input[type='button']").click(callback);
this.parent().find("select").change(callback);
return this;
};
And then in your onready handler:
$("ul.dropdown_nav").ddnav();
But I would point out that these are terrible for usability. Better to use a list and show people all of the options at once, and it's better to not navigate away after a selection and/or require a different button to be pushed to get to where they want.
I think you're best off never using the above (and I wrote the code!)
