Hi, On a menu I am using, I need help on adding a delay to my CSS Menu before it collapses. Using IE, you cannot select any submenu items apart from the bottom one. A link is attached.


Firefox is fine, i can select any of my submenu items.

Also, I am using csshover.htc file to enable my hovers to work in IE. Is there anything I can add into that to get it to work properly under IE?

CSSHover.htc file contents:

<attach event="ondocumentready" handler="parseStylesheets" />

<script>

var csshoverReg = /(^|\s)(([^a]([^ ]+)?)|(a([^#.][^ ]+)+))hover|active)/i,

currentSheet, doc = window.document, hoverEvents = [], activators = {

onhover:{on:'onmouseover', off:'onmouseout'},

onactive:{on:'onmousedown', off:'onmouseup'}

}



function parseStylesheets() {

if(!/MSIE (5|6)/.test(navigator.userAgent)) return;

window.attachEvent('onunload', unhookHoverEvents);

var sheets = doc.styleSheets, l = sheets.length;

for(var i=0; i<l; i++)

parseStylesheet(sheets[i]);

}

function parseStylesheet(sheet) {

if(sheet.imports) {

try {

var imports = sheet.imports, l = imports.length;

for(var i=0; i<l; i++) parseStylesheet(sheet.imports[i]);

} catch(securityException){}

}



try {

var rules = (currentSheet = sheet).rules, l = rules.length;

for(var j=0; j<l; j++) parseCSSRule(rules[j]);

} catch(securityException){}

}



function parseCSSRule(rule) {

var select = rule.selectorText, style = rule.style.cssText;

if(!csshoverReg.test(select) || !style) return;



var pseudo = select.replace(/[^:]+[a-z-]+).*/i, 'on$1');

var newSelect = select.replace(/(\.([a-z0-9_-]+):[a-z]+)|(:[a-z]+)/gi, '.$2' + pseudo);

var className = (/\.([a-z0-9_-]*on(hover|active))/i).exec(newSelect)[1];

var affected = select.replace(/hover|active).*$/, '');

var elements = getElementsBySelect(affected);

if(elements.length == 0) return;



currentSheet.addRule(newSelect, style);

for(var i=0; i<elements.length; i++)

new HoverElement(elements[i], className, activators[pseudo]);

}



function HoverElement(node, className, events) {

if(!node.hovers) node.hovers = {};

if(node.hovers[className]) return;

node.hovers[className] = true;

hookHoverEvent(node, events.on, function() { node.className += ' ' + className; });

hookHoverEvent(node, events.off, function() { node.className = node.className.replace(new RegExp('\\s+'+className, 'g'),''); });

}

function hookHoverEvent(node, type, handler) {

node.attachEvent(type, handler);

hoverEvents[hoverEvents.length] = {

node:node, type:type, handler:handler

};

}



function unhookHoverEvents() {

for(var e,i=0; i<hoverEvents.length; i++) {

e = hoverEvents[i];

e.node.detachEvent(e.type, e.handler);

}

}



function getElementsBySelect(rule) {

var parts, nodes = [doc];

parts = rule.split(' ');

for(var i=0; i<parts.length; i++) {

nodes = getSelectedNodes(parts[i], nodes);

} return nodes;

}

function getSelectedNodes(select, elements) {

var result, node, nodes = [];

var identify = (/\#([a-z0-9_-]+)/i).exec(select);

if(identify) {

var element = doc.getElementById(identify[1]);

return element? [element]:nodes;

}



var classname = (/\.([a-z0-9_-]+)/i).exec(select);

var tagName = select.replace(/(\.|\#|\[a-z0-9_-]+/i, '');

var classReg = classname? new RegExp('\\b' + classname[1] + '\\b'):false;

for(var i=0; i<elements.length; i++) {

result = tagName? elements[i].all.tags(tagName):elements[i].all;

for(var j=0; j<result.length; j++) {

node = result[j];

if(classReg && !classReg.test(node.className)) continue;

nodes[nodes.length] = node;

}

}



return nodes;

}

</script>

Any help appreciated, thanks
