all want on hovering on search #search_drop should shown not happening

you cannot hover on non-displayed node. display:none -> not on page. so, cannot hover on this. same applies hidden but, can alter other properties. example,

#search {  border : 1px green solid; } #search:hover {  border : 5px red solid; }  <div id="search"> abcdefgh abcdefgh abcdefgh </div>
