Set width of dropdown element in HTML select dropdown options

Question

I am working on a website that involves automatically populating a select box using a PHP script. This all works fine except the problem is that what I am using to populate the text box have very long titles (they are journal articles and presentation titles). The dropdown box extends to the width of the longest element, which stretches off the edge of the screen, therefore making the scrollbar impossible to reach. I have tried various methods of trying to manually set the dropdown box using CSS to a particular width, but so far to no avail. The best I have accomplished it to set the Select box to a certain width but the dropdown menu itself is much, much wider.

Any tips on this would be greatly appreciated.

EDIT:

It turns out that the following CSS line works in all of the primary browsers except for Google Chrome (which is what I was testing the page in). If a solution for Chrome is known, that would be good to know about.

select, option { width: __; }

Answer 1

You can style (albeit with some constraints) the actual items themselves with the option selector:

select, option { width: __; }

This way you are not only constraining the drop-down, but also all of its elements.

Answer 2

On the server-side:

1. Define a max length of the string
2. Clip the string
3. (optional) append horizontal ellipsis

Alternative solution: the select element is in your case (only guessing) a single-choice form control and you could use a group of radio buttons instead. These you could then style with better control. If you have a select[@multiple] you could do the same with a group of checkboxes instead as they can both be seen as a multiple-choice form control.
