ultags[t].parentNode.onmouseover = function () {  this.getElementsByTagName("ul")[0].style.left = this.parentNode.offsetWidth + submenuoffset + "px";  this.getElementsByTagName("ul")[0].style.display = "block";  this.getElementsByTagName("ul")[0].style.position = "absolute";  this.getElementsByTagName("ul")[0].style.top = this.parentNode.offsetTop - this.offsetTop + "px"; }
