Large text values in combo box

I have a requirement to display long values (1000 - 2000 characters in a drop down control. I am trying this with DropDownByKey and DropDownByIndex. It is not displaying complete value and occupying complete screen drop down box is opened.

I would like to have each value to be wrapped into multiple rows so that user can see complete value it will not be too lengthy when expanded.

I have thought of EVS but it is not relevant in this case. OVS will be too heave for this requirement. Can anyone suggest better solution to achieve this.

Thanks,

Kishore.
