How to Adjust Drop-Down List Width in Internet Explorer?

IE Drop-Down List Width Control

Problem:

In Internet Explorer (IE), drop-down lists inherit the width of their parent drop-down box, resulting in an unwieldy appearance when the longest option selector extends beyond the width of the drop-down box.

Solution: CSS- and JavaScript-Based Workaround

To overcome this issue, a combination of CSS and jQuery can be employed to set different widths for the drop-down box and its list of options:

$(document).ready(function() {
  $('select.wide')
    .bind('focus mouseover', function() { $(this).addClass('expand').removeClass('clicked'); })
    .bind('click', function() { $(this).toggleClass('clicked'); })
    .bind('mouseout', function() { if (!$(this).hasClass('clicked')) { $(this).removeClass('expand'); }})
    .bind('blur', function() { $(this).removeClass('expand clicked'); });
});

Apply the following CSS:

select {
  width: 150px; /* or desired width */
}
select.expand {
  width: auto;
}

Assign the class 'wide' to the affected drop-down elements:

<select class="wide">
  ...
</select>

This approach ensures that the drop-down box retains a fixed width while allowing the drop-down list to expand dynamically, accommodating the longest available selector.
