Hi.., I have a listbox ​​that is dynamically loaded from a table of a Database (mysql)​.
I put a width of 100px to the list but when the list is displayed (drop down) the width don't keep in 100px. When drop down, the width of list is set to the width corresponding to the register with more characters found in the table. I mean, it gets wider. I need the list remains with equal width, when open and when closed.

how do you do the drop down list has the same width when the list is closed ?
