Define tooltip for datalistboxmultiple option

ribeiroi

Hello,

The text of an option label is too big to fit the space. I was thinking about including a tooltip that shows when cursor hover.

How can I achieve that?

I can't increase control's width.

Current code is:

<dmf_tips:datalistboxmultiple name="lst_aval_values" size="10" height="100" width="320">
<dmf:dataoptionlist >
<dmf:option name="opt_search" datafield="code" labeldatafield="english_name"/>
</dmf:dataoptionlist>
</dmf_tips:datalistboxmultiple>
