# How to set the Width of Select Options in HTML & CSS

Set the width CSS property of the select element and its option elements to set the width of a select dropdown using CSS.

If setting the property has no effect, you might have to use the !important flag.

Copied!
DOCTYPE html> html lang="en"> head> meta charset="UTF-8" /> style> select  width: 300px; > select option  width: 300px; > style> head> body> h2>bobbyhadz.comh2> select name="languages" id="language-select"> option value="">--Choose an option--option> option value="javascript">JavaScriptoption> option value="typescript">TypeScriptoption> option value="python">Pythonoption> option value="java">Javaoption> option value="php">PHPoption> option value="php"> A very long select option abc 123 option> select> body> html>

Notice that we set the width of the select element and all of its option elements to the same value — 300px.

Copied!
select  width: 300px; > select option  width: 300px; >

If setting the width has no effect in your case, you might have to use the !important flag.

Copied!
select  width: 300px !important; > select option  width: 300px !important; >

The !important flag allows you to override styles that have higher precedence.

You will most likely want to set the width of the select and its option elements to the same value.

Here is an example of setting the width of the select element and its option elements to different values.

Copied!
select  width: 150px; > select option  width: 300px; >

Setting the width of the select element to a lower value than the width of the option elements is most likely not what you want.

When a wider option is selected, its value is truncated.

Here is an example that sets the width of the select element to 300px and the width of its option elements to 150px .

Copied!
select  width: 300px; > select option  width: 150px; >

# The width of your option elements might exceed the width of your select

In some cases, you might have very wide option elements.

You can try to set the max-width CSS property on the select element but this likely won’t work.

Copied!
select  width: 300px; max-width: 300px; >

Most browsers will still want to display the entire text of the option element, so setting the width CSS property might not have an effect.

In these cases, it’s best to use JavaScript to trim the text of the option element.

Here is the HTML for the example.

Copied!
DOCTYPE html> html lang="en"> head> meta charset="UTF-8" /> style> body  margin: 100px; > select  width: 300px; > style> head> body> h2>bobbyhadz.comh2> select name="languages" id="language-select"> option value="">--Choose an option--option> option value="javascript">JavaScriptoption> option value="typescript">TypeScriptoption> option value="python">Pythonoption> option value="java">Javaoption> option value="php">PHPoption> option value="php"> bobbyhadz.com bobbyhadz.com bobbyhadz.com bobbyhadz.com bobbyhadz.com bobbyhadz.com bobbyhadz.com bobbyhadz.com bobbyhadz.com option> select> script src="index.js"> script> body> html>

And here is the code for the index.js file.

Copied!
const optionElements = document.querySelectorAll('option'); Array.from(optionElements).forEach(element =>  if (element.textContent.length > 35)  element.textContent = element.textContent.slice(0, 35) + '. '; > >);

We used the document.querySelectorAll method to select the option elements on the page.

We then converted the collection to an array using Array.from and used the Array.forEach to iterate over the array.

On each iteration, we check if the textContent of the current option element is greater than 35.

If the condition is met, we use the String.slice method to truncate the text to the first 35 characters and add an ellipsis . .

You might have to play around with the width of the select element and how many characters you want to display in your option elements depending on your use case.

# Set the Width of a Select Option in HTML & CSS using inline styles

If you weren’t able to set the width of the select element and its options using external styles, try using inline styles.

Copied!
DOCTYPE html> html lang="en"> head> meta charset="UTF-8" /> head> body> h2>bobbyhadz.comh2> select name="languages" id="language-select" style="width: 240px" > option style="width: 240px" value=""> --Choose an option-- option> option style="width: 240px" value="javascript"> JavaScript option> option style="width: 240px" value="typescript"> TypeScript option> option style="width: 240px" value="python">Pythonoption> option style="width: 240px" value="java">Javaoption> option style="width: 240px" value="php">PHPoption> option style="width: 240px" value="php"> A very long select option abc 123 option> select> body> html>

The example sets the width of the select element and its options using inline styles.

Copied!
select name="languages" id="language-select" style="width: 240px" > option style="width: 240px" value=""> --Choose an option-- option> select>

The width of both elements is set to 240px.

Inline styles have higher precedence than external stylesheets, so using this approach might work even if the previous approach didn’t work.

If none of the suggestions worked, you can try to use the !important flag which has the highest precedence.

Copied!
select  width: 300px !important; > select option  width: 300px !important; >

css — set max-width for select

I have a form with a drop down list of venues and a submit button. They are supposed to be on the same line, but since the list of venues is dynamic, it could become too long and push the button down. I was thinking of setting a max-width property to the select, but I’m not clear whether this will work in all browsers. Do you have any suggestions on a workaround?

.searchform select < max-width: 320px; >.searchform input.submitButton

If the venues are generated on the server side, you can use your server-side scripting to cut them down to a specific maximum character count.

When using pure CSS I’d also try setting overflow:hidden , both on the select and the option elements. Also try setting max-width on the option element. When it works in all non-IE, you can use the usual scripts to add max-width support for IE.

How can I set the width of HTML element, without considering the width of each option

Actually I know the select box width is set by the longest option in the list, but I want to increase the length (width) of a select html element. I also searched and I understand this code style=»max-width:70%» may work but it doesn’t work for me. The code below is mine:

you should use width attribute instead of max-width . correct your code to below sample:

You have to use css property min-width for increasing width of dropdown irrespective of the width of options.

Separation of concerns—keeping styling information in a stylesheet—is also far better than an inline style attribute.

As a new user thanks for your contribution. Note however that your answer is a duplicate of Sheida’s, which I’m sure you did not see when posting your answer. Furthermore you answer lacks in details. Other people have to parse the HTML in your code block and compare it with the one in the question to understand what do you mean. It would be much more helpful to provide a textual description of the solution and not just the code. Even better with a couple links to the relevant documentation. If you keep this in mind you’ll provide more valuable answers.
