Multi select box

is there any way I can increase the width of the multi select box ?

I have a default multi select box . I populate multi select box with database values. but records are not completely readable. I wish to increase the width of the multi select box so that all records are readable properly.

What I need to do ?

Normally it just expands to the width of the longest item. Have you set a width on it yourself?

EDIT: have you considered checkboxes instead? They are easier to select.
