Menu using 2 js functions.
Hello guys! I've got a little problem with a menu I am making. I want it to have expandable and collapsable items. With a lot of help from some people here, I have it the way I want it. Now, my next problem is the following. I want to make the menu dragable too. I have found a js function that does the trick, remembers in a cookie where the menu was dragged last etc... However, by adding this dragging feature, I cannot open the menu anymore. The js files do not crash with each other though, since if I make for example the logo draggable, the menu opens/closes fine.
Together with jQuery, this is my expand/collapse code:
Code:
$(document).ready(function() {
// By default, reveal the first menu item automatically.
// If JavaScript is loaded with menu.js?show=something
// And the "something" item exists in the menu, then that
// item will be revealed instead.
var szDiv = 'div.menu > h3:not(:first) + div';
var aShow = $('head > script[src^="menu.js"]:first').attr('src').match(/show=([^&]*)/);
if (aShow && aShow[1] != "" && $('div.menu > h3:contains("' + aShow[1] + '")').length > 0) {
szDiv = 'div.menu > h3:not(:contains("' + aShow[1] + '")) + div';
}
$(szDiv).hide();
$('div.menu > h3').click(function() {
$(this).next('div').slideToggle('fast', function() {
$(this).siblings('div:visible').slideUp('fast')
});
});
});
And this is my dragable code, downloaded from dhtmlgoodies:

What can I do to make these both work together? Thanks in advance, and I'm aware, I posted a lot of code. |
