ik heb een dropdown-menu in css en dit lukt volledig, alleen heb ik een probleempje in IE. Wanneer ik uit het menu ga in IE dan verdwijnt het menu, dit mag echter niet (in FF blijft het menu wel staan.

iemand een idee hoe ik dit kan oplossen??

Mijn css code:

/*start menu*/


#dropmenudiv{
position:absolute;
border:1px solid black;
border-bottom-width: 0;
font:normal 12px Verdana;
line-height:18px;
z-index:100;
}

#dropmenudiv a{
width: 100%;
display: block;
text-indent: 3px;
border-bottom: 1px solid black;
padding: 1px 0;
text-decoration: none;
font-weight: bold;
}

#dropmenudiv a:hover{ /*hover background color*/
background-color: yellow;
}

/*einde menu*/


misschien is het ook handig om de bijhorende javascript te hebben:

Voor een goed dropdown menu heb je helemaal geen javascript nodig. Zie:
