select box issue in IE when using BOXOVER.js tool tip

I am using boxover.js tool tip:

The tool tip works well with all the elements except SELECT box in IE.

I have a code where i need to show some image as a tool tip on selecting the option in a select box.

Ex:

<select name="categoryName" id="categoryName" style="width:50%;" size="10" >
    <option value="">--Select Category--</option>
    <option title="cssbody=[bdycss] cssheader=[hdrcss] header=[Category] body=[<center><p&开发者_如何学Pythongt;<img src='icon1.png'></p>]" value="1">category1</option>
    <option title="cssbody=[bdycss] cssheader=[hdrcss] header=[Category] body=[<center><p><img src='icon2.png'></p>]" value="2">category2</option>
    <option title="cssbody=[bdycss] cssheader=[hdrcss] header=[Category] body=[<center><p><img src='icon3.png'></p>]" value="3">category3</option>      
</select>

Pls help me in fixing this issue. Thanks in advance.

IE6 does not [IE7 onwards it does] support title property for OPTION tag. You can have same title for all OPTIONs by setting title attribute in SELECT tag.

Another option is to have DHTML popup as tooltip.
