How to wrap text into a select drop down menu

When we have specific width (e.g.: 400px) but very long string of text to display (e.g.: Strategic and Cooperative Action for the Conservation of Biodiversity in North America), the text is not completely showing (e.g.: Strategic and Cooperative Action for the Conservation of Bio).

I am pretty sure somebody developed a method to show the string of text in 2 lines or something equivalent to show all the text. But, after trying to search through the NET, I did not have a lot of success.

So, anybody have heard about a method to display long text in two lines into a select drop down menu?

Thank's!
