    [Javascript] [CSS] Menù a tendina con hover contenuto, tab active

    Non sapevo che scrivere ragazzi nel titolo, scusate se non è molto inerente :bho:

    Comunque ho un problema, con un menù a tendina e questo me lo chiedo da sempre.

    Allora, utilizzo questo javascript per il mio menù:

    //Chrome Drop Down Menu v2.01- Author: Dynamic Drive
    //Last updated: November 14th 06- added iframe shim technique
    
    var cssdropdown={
    disappeardelay: 250, //set delay in miliseconds before menu disappears onmouseout
    disablemenuclick: true, //when user clicks on a menu item with a drop down menu, disable menu item's link?
    enableswipe: 1, //enable swipe effect? 1 for yes, 0 for no
    enableiframeshim: 1, //enable "iframe shim" technique to get drop down menus to correctly appear on top of controls such as form objects in IE5.5/IE6? 1 for yes, 0 for no
    
    //No need to edit beyond here////////////////////////
    dropmenuobj: null, ie: document.all, firefox: document.getElementById&&!document.all, swipetimer: undefined, bottomclip:0,
    
    getposOffset:function(what, offsettype){
    var totaloffset=(offsettype=="left")? what.offsetLeft : what.offsetTop;
    var parentEl=what.offsetParent;
    while (parentEl!=null){
    totaloffset=(offsettype=="left")? totaloffset+parentEl.offsetLeft : totaloffset+parentEl.offsetTop;
    parentEl=parentEl.offsetParent;
    }
    return totaloffset;
    },
    
    swipeeffect:function(){
    if (this.bottomclip<parseInt(this.dropmenuobj.offsetHeight)){
    this.bottomclip+=10+(this.bottomclip/10) //unclip drop down menu visibility gradually
    this.dropmenuobj.style.clip="rect(0 auto "+this.bottomclip+"px 0)"
    }

    ```Invece questo è il codice CSS:
    
    

    ul#minitabs{
    list-style: none;
    font-weight: bold;
    text-align: center;
    white-space: nowrap;
    }
    ul#minitabs li {
    display: inline;
    padding: 4px;
    }
    ul#minitabs li a.minitabs{
    text-decoration: none;
    padding: 10px;
    font-size: 12px;
    border-right: solid 1px #50a3e5;
    border-left: solid 1px;
    }
    ul#minitabs li a.minitabs:hover{
    background: url(images/blue_life/bg_topnav_hover.gif) top repeat-x;
    color: #FFFFFF;
    }
    /* ## ChromeStyle ## DropDown Menu ## */
    .dropmenudiv {
    position: absolute;
    text-align: left;
    vertical-align: middle;
    margin-left: 0px;
    margin-top: 0px;
    border: 1px solid #3a93cb;
    line-height: 18px;
    z-index: 100;
    width: 105px;
    visibility: hidden;
    font-size: 12px;
    -moz-border-radius-bottomleft: 3px;
    -moz-border-radius-bottomright: 3px;
    }
    .dropmenudiv a.link_dropmenu {
    background: url(images/blue_life/bg_dropmenu.gif) no-repeat left;
    display: block;
    height: 21px;
    text-indent: 3px;
    border-bottom: 1px solid #dedede;
    padding: 2px 0 0 13px;
    text-decoration: none;
    font-weight: bold;
    color:;
    text-align: left;
    }
    .dropmenudiv a.link_dropmenu:hover {
    color: #5cb000;
    }

    
    [html]<ul id="minitabs">
        <li><a href="#" rel="dropmenu_24_2_1" class="minitabs">Menu <img src="templates/blue_life/images/blue_life/menu_arrow_down.gif" alt=""></a><div style="top: 123px; left: 437px; clip: rect(0pt, auto, 10px, 0pt); visibility: hidden;" id="dropmenu_24_2_1" class="dropmenudiv"><a class="link_dropmenu" href="#">Link</a></div></li></ul>[/html]Ora, se io io passo nel nome **Menu** questo è in *:hover* ma se vado su un link che appere nel menu a tendina in basso, per esempio **Link**, la tab Menu torna normale e non rimane attiva.
    
    Come posso risolvere questo problema ragazzi? Grazie in anticipo :D
