How to display one DIV over another DIV in IE6?

问题

I am writting some html code which have following structure

<div style="position:relative">
<form>
<table>
<tr>
<td> <div id="Upper_Element" style="position:absolute;z-index:10"></div> </td>
</tr>
<tr>
<td> <div id="Lower_Element" style="position:absolute;z-index:-1"></div> </td>
</tr>
</table>
</form>
</div>

here Upper_Element is a YUI autocomplete text box (where suggestion are displayed when user enters anything like google) and Lower_Element is normal drop down box(<select>). In IE6 , When autocomplete suggestion are displayed Lower_Element is displayed over the suggestions list . In other browser like IE8 its working fine. I tried position and z-index attributes but no luck.

Please let me know what else can be tried.

Thanks in advance !

回答1:

What do you mean by "Lower_Element is a normal drop down box"? Is it a <select> element or a <div> as in your example? If it is a <select> then you are seeing a very old bug that affects IE6 and has been asked/solved many times before, for example Z-Index problems with IE6 and html <select> element and iframe shimming or ie6 (and below) select z-index bug

Use position: absolute and z-index attribute to position one element above another

Code

<div style="position:absolute"> ... </div>

Positioning:

<div style="position:absolute; top: 100px; left: 100px"> ... </div>

UPD

<div style="position:relative">
  <form>
    <div id="upper_element" style="position:absolute; z-index:2">I am top level div!</div>
    <div id="lower_element" style="position:absolute; z-index:1">I am on the bottom of life</div>
  </form>
</div>
