IE 7 css menu glitch

Posted on 2009-04-20
Last Modified: 2012-08-13
Hi Experts,

I have a css menu that is working correctly in all browsers tested except IE7. The issue occurs when the cursor travels over the <a href> to make a hidden <div> appear. The div appears but as the cursor moves to highlight the next menu option the div disappears again.

I have been through my code again and again but can't seem to see what IE doesn't like.

Please see the example here:

Thank you for any advise to can offer.


width: 99%;

font-weight: bold;


.chromestyle:after{ /*Add margin between menu and rest of content in Firefox*/

content: "."; 

display: block; 

height: 0; 

clear: both; 

visibility: hidden;


.chromestyle ul{

border: 1px solid #BBB;

width: 100%;

background: url(chromebg.gif) center center repeat-x; /*THEME CHANGE HERE*/

padding: 4px 0;

margin: 0;

text-align: center; /*set value to "left", "center", or "right"*/


.chromestyle ul li{

display: inline;


.chromestyle ul li a{

color: #494949;

padding: 4px 7px;

margin: 0;

text-decoration: none;

border-right: 1px solid #DADADA;


.chromestyle ul li a:hover, .chromestyle ul li a.selected{ /*script dynamically adds a class of "selected" to the current active menu item*/

background: url(chromebg-over.gif) center center repeat-x; /*THEME CHANGE HERE*/

//** Chrome Drop Down Menu- Author: Dynamic Drive (

//** Updated: July 14th 06' to v2.0

	//1) Ability to "left", "center", or "right" align the menu items easily, just by modifying the CSS property "text-align".

	//2) Added an optional "swipe down" transitional effect for revealing the drop down menus.

	//3) Support for multiple Chrome menus on the same page.

//** Updated: Nov 14th 06' to v2.01- added iframe shim technique

//** Updated: July 23rd, 08 to v2.4

	//1) Main menu items now remain "selected" (CSS class "selected" applied) when user moves mouse into corresponding drop down menu. 

	//2) Adds ability to specify arbitrary HTML that gets added to the end of each menu item that carries a drop down menu (ie: a down arrow image).

	//3) All event handlers added to the menu are now unobstrusive, allowing you to define your own "onmouseover" or "onclick" events on the menu items.

	//4) Fixed elusive JS error in FF that sometimes occurs when mouse quickly moves between main menu items and drop down menus

//** Updated: Oct 29th, 08 to v2.5 (only .js file modified from v2.4)

	//1) Added ability to customize reveal animation speed (# of steps)

	//2) Menu now works in IE8 beta2 (a valid doctype at the top of the page is required)

disappeardelay: 250, //set delay in miliseconds before menu disappears onmouseout

    You have a closing </div> tag before the submenu. The parent <div> needs to encompass both the top-level menu item and the sub-items. (You're also missing closing </li> tags on your menu items.)

    I changed it as follows, and it works in IE7 on my local machine. Give this a try:

    <DIV class=chromestyleOUT id=chromemenu>
      <FORM id=user-login-form style="FLOAT: left" action=./Login_Script.php
      method=post><INPUT id=Username
      onfocus="if(this.value=='Username') this.value=''" size=12 value=Username
      name=Username> <INPUT id=Password
      onfocus="if(this.value=='aaaaaaaa') this.value=''" type=password size=12
      value=aaaaaaaa name=Password> <INPUT class=bodyTxtSmallWhite
      style="MARGIN: 0px 30.5em 0px 0px" onclick=./Login_Script.php type=image
      value=Login name=Submit> </FORM>
      <LI><A href="">Home</A></LI>
      <LI><A href="">New Content</A> </LI>

      <LI><A href=""
      rel=dropmenu1>Help</A> </LI>
      <!--1st drop down menu -->
    <DIV class=dropmenudivOUT id=dropmenu1 style="WIDTH: 150px">

    Hi slovisa, Thanks for taking a look at this. I have cut 'n' pasted the code you posted but it's still disappearing when I come off the btn on my IE.
    My version is: IE 7 7.0.5730.13

    The code that you sent is up there now. Is it working for you?

    Accepted Solution

    Slovisa, Please don't spend anymore of your time on this. We are going to drop this menu as it's just not working well. We have spent a long time trying to get it working in all main browsers and it just isn't woth the time. We will run with a standard set of links.

    Thank you for your help.
