Hinzufügen einer Kategorie der 3. Ebene zur Bildlauf-Dropdown-Liste

Ich habe eine lange Dropdown-Liste der Unterkategorie, die auch die Unterkategorie der dritten Ebene enthält. Ich habe mit CSS-Tricks Referenz hinzugefügt: https://css-tricks.com/long-dropdowns-solution/ Jetzt bin ich nicht in der Lage, Kategorie der dritten Ebene anzuzeigen ... es muss Seite der Unterkategorie anzeigen. gib mir die richtigen Richtlinien

für die dritte Ebene

        <script>
var maxHeight = 300;
var maxwidth
jQuery.noConflict();
jQuery(function(){

jQuery("li.level0").hover(function() {

var jQuerycontainer = jQuery(this),
jQuerylist = jQuerycontainer.find("ul.level0"),
jQueryanchor = jQuerycontainer.find("a"),
height = jQuerylist.height() * 1.1, // make sure there is enough room at the bottom
multiplier = height / maxHeight; // needs to move faster if list is taller

// need to save height here so it can revert on mouseout
jQuerycontainer.data("origHeight", jQuerycontainer.height());

// so it can retain it's rollover color all the while the dropdown is open
jQueryanchor.addClass("hover");

// make sure dropdown appears directly below parent list item
jQuerylist
.show()
.css({

paddingTop: jQuerycontainer.data("origHeight"),
position:'absolute',
});

// don't do any animation if list shorter than max
if (multiplier > 1) {
jQuerycontainer
.css({
height: maxHeight,
overflow: "hidden",



})
.mousemove(function(e) {
var offset = jQuerycontainer.offset();
var relativeY = ((e.pageY - offset.top) * multiplier) - (jQuerycontainer.data("origHeight") * multiplier);
if (relativeY > jQuerycontainer.data("origHeight")) {
jQuerylist.css("top", -relativeY +jQuerycontainer.data("origHeight"));
};
});
}

}, function() {

var jQueryel = jQuery(this);

// put things back to normal
jQueryel
.height(jQuery(this).data("origHeight"))
.find("ul")
.css({ })
.hide()
.end()
.find("a")
.removeClass("hover");

})});
jQuery (function() {
jQuery("li.level1").hover(function() {

var jQuerycontainer = jQuery(this),
jQuerylist = jQuerycontainer.find("ul.level1"),
jQueryanchor = jQuerycontainer.find("a"),
height = jQuerylist.height() * 1.1, // make sure there is enough room at the bottom

})});

//Add down arrow only to menu items with submenus
// jQuery(".nav-primary > li:has('ul')").each(function() {
// jQuery(this).find("a:first").append("<img src='images/down-arrow.png' />");
// });
