How can change width of dropdown list?

Question

I have a listbox and I want to decrease its width.

Here is my code:

<select name="wgtmsr" id="wgtmsr" style="width: 50px;">
  <option value="kg">Kg</option>
  <option value="gm">Gm</option>
  <option value="pound">Pound</option>
  <option value="MetricTon">Metric ton</option>
  <option value="litre">Litre</option>
  <option value="ounce">Ounce</option>
</select>

This code works on IE 6 but not in Mozilla Firefox (latest version). Can anybody please tell me how I can decrease the width of the dropdown list on Firefox?

Why don't you change the width according to the width of the content? https://stackoverflow.com/questions/20091481/auto-resizing-the-select-element-according-to-selected-options-width/55343930#55343930 — João Pimentel Ferreira, May 03 '20 at 19:27

Try this code:

<select name="wgtmsr" id="wgtmsr">
<option value="kg">Kg</option>
<option value="gm">Gm</option>
<option value="pound">Pound</option>
<option value="MetricTon">Metric ton</option>
<option value="litre">Litre</option>
<option value="ounce">Ounce</option>
</select>

CSS:

#wgtmsr{
 width:150px;   
}

If you want to change the width of the option you can do this in your css:

#wgtmsr option{
  width:150px;   
}

Maybe you have a conflict in your css rules that override the width of your select

How is that any different than what the OP has? – Chris Dec 18 '12 at 11:13

Inline `style` definitions override every other styling (unless there's `!important`), so I don't think so. The OP's original code works fine even on Firefox 17.0.1. – Chris Dec 18 '12 at 11:15

@Abody97 maybe he has a conflict in his css – Alessandro Minoccheri Dec 18 '12 at 11:17

@Chris or unless you override them with `element[style]` in your css. – Pere Dec 31 '14 at 11:50

FYI This does not seem to make any difference on Chrome or IE11, it does however as the OP asked work for Firefox, I was looking for something a little more generic... :( – PJUK Nov 17 '15 at 16:46
select {} never worked but using the name worked great! – AShah Mar 30 '21 at 21:15
It will not work if the option length is long. – Nandeep Barochiya Dec 03 '21 at 07:05

The dropdown width itself cannot be set. It's width depend on the option-values. See also here ( jsfiddle.net/LgS3C/ )

How the select box looks like is also depending on your browser.

You can build your own control or use Select2 https://select2.org

This:

<select style="width: XXXpx;">

XXX = Any Number

Works great in Google Chrome v70.0.3538.110

try the !important argument to make sure the CSS is not conflicting with any other styles you have specified. Also using a reset.css is good before you add your own styles.

select#wgmstr {
    max-width: 50px;
    min-width: 50px;
    width: 50px !important;
}

or

<select name="wgtmsr" id="wgtmsr" style="width: 50px !important; min-width: 50px; max-width: 50px;">

Did you actually try what you're suggesting? If you did, you might notice that the OP's original code already works. – Chris Dec 18 '12 at 11:17
that is why i am suggesting him to use the `!important` argument to make sure the code is not conflicting with other styles. – Amyth Dec 18 '12 at 11:19
Adding `!important` is the only thing which worked for me. I always forget about it. – Tass Nov 02 '16 at 14:31

Create a css and set the value style="width:50px;" in css code. Call the class of CSS in the drop down list. Then it will work.

If you want to control the width of the list that drops down, you can do it as follows.

CSS

#wgtmsr option {
    width: 50px;
}

This doesn't seem to be working, at least not in Chrome. – Maximillian Laumeister Feb 17 '16 at 19:18

This worked for me:

ul.dropdown-menu > li {
    max-width: 144px;
}

in Chromium and Firefox.
