ListSelect: I want to set tooltips for each HTML Option

I can create ListSelect just fine, set the caption. But I’d like to be able to set the tooltip for each entry

In the HTML I could just set the title attribute.

Is there any proper way to set this or any generic attribute for the OPTION HTML?

I can’t see anything obvious from the API.

Thanks.

You mean setting the description (i.e. tooltip) for Item objects? I don’t think that’s supported.

Yes, that’s exactly what I want. If its not suported then it needs to be.
