Menu verticale espandibile a tre livelli a scomparsa

[franco12345678]

Da un poco di tempo ho scaricato e poi odificato un menu a tre livelli verticale.
Si tratta di un menù a scomparsa che usa accordion.js e jquery.js.
Ho un problema che non riesco a risolvere:
Le voci di menù dirette, cioè che non hanno sottomenù, hanno bisogno di un doppio click per l'incarsi alla pagina richiesta e io vorrei si aprissero con un solo click.
Questo il il link per l'esempio http://www.franco12345678.altervista.org/
Grazie

se esistesse la possibilità di siulare con un click un secondo click?

invio anche il file accordion.js

jQuery.fn.extend({
	// nextUntil is necessary, would be nice to have this in jQuery core
	nextUntil: function(expr) {
	    var match = [];
	
	    // We need to figure out which elements to push onto the array
	    this.each(function(){
	        // Traverse through the sibling nodes
	        for( var i = this.nextSibling; i; i = i.nextSibling ) {
	            // Make sure that we're only dealing with elements
	            if ( i.nodeType != 1 ) continue;
	
	            // If we find a match then we need to stop
	            if ( jQuery.filter( expr, [i] ).r.length ) break;
	
	            // Otherwise, add it on to the stack
	            match.push( i );
	        }
	    });
	
	    return this.pushStack( match );
	},
	// the plugin method itself
	Accordion: function(settings) {
