Unable to make Combo popup box resize

I have lot of combo box in my HTML page, and unable to resize the combo popup box. Is there a way to dynamically resize the combo popup box ? The text inside the combo popup box truncates after a fixed size.

If I use the <style> #myCombo ... </style> tag inside the HTML, I will need a correspoding style for each of the combo box usage within the HTML page. Is there a way to overcome this within the <script> ...... </script> tags ?

obj.getPopupTemplate().setStyle("width", "300px");

Thanks a ton Alex, it worked. Thanks once again.

Is it possible to do this via a css entry?

I have something like: {left: 100px; top: 335px; width: 280px; height: 18px;}

The control itself is that size but the popup shows a smaller box. Is there something I can add to get both or do I need the template entry?
