Customize the List Box Appearance for a Specific HTML Item (Option)

Question

Customize the List Box Appearance for a Specific HTML Item (Option)

I am working on achieving a specific behavior.

When using a listBox (or comboBox), the first element (such as "choose one") should have a unique style.

Here is an example of code to test:

<style type="text/css">
 .testX {font-style: italic;}
</style>

(...)

<select name="name" id="id">

<option class="testeX" selected="selected" value="#">
    <p class="testX">Choose One</p>
</option>
<option value="TestValue">
    TestValue
</option>

I can observe this behavior in Firefox, but not in Chrome. When I expand my listBox and select 'Choose One', the field does not display the italic style.

Is there a way to achieve this using only HTML and CSS, or do I need to utilize jQuery?

Thank you.

Styling form elements can be quite challenging, as consistency across browsers and operating systems is often hard to achieve. One approach I've found effective is to use javascript, typically jQuery, to hide the original form element and create a custom design using divs and spans instead. This allows for greater flexibility in styling options.

However, it's important to consider the necessity of deviating from standard form elements. Straying too far from convention can impact usability negatively.

In the realm of HTML4, an OPTION element is limited to containing only PCDATA, plain character data without any child elements. These characters will be parsed, including entities.

http://www.w3.org/TR/html401/interact/forms.html#edef-OPTION

With the evolution to HTML5, solely text content is permissible within an OPTION.

http://dev.w3.org/html5/spec/the-option-element.html

To put it simply, utilizing anything beyond text inside an OPTION results in invalid HTML that may pose parsing challenges for browsers. Until encountering this query, I wasn't aware of any browser capable of rendering HTML elements within an OPTION tag.

For a unique approach, consider utilizing the 'first-child' pseudo element.

 <style type="text/css">
       select#id option:first-child {font-style: italic;}
 </style>

Remember, paragraph tags should not be nested inside <option> tags - they should only contain plain text.

Keep in mind that styling on <option> tags has limitations, as not all browsers support it. You may have better success with alternative styling methods like background colors. Another option is to use JavaScript and custom HTML to mimic the behavior of a regular <select> box.

italic formatting may not display correctly in Chrome and Opera browsers. Please refer to this link for more information.

There are various design options available for select elements.

<select name="name" id="id">
    <option style='font-style: italic; font-weight:bold;' selected="selected" value="#">
        <span>Choose One</span>
    </option>
    <optgroup label="Option group 1">
        <option value="TestValue">    TestValue</option>
        <option value="TestValue">    TestValue</option>
        <option value="TestValue">    TestValue</option>
    </optgroup>
</select>

CSS styling:

select option {
    background: none repeat scroll 0 0 #E5E3E3;
    border: 1px dotted #CCCCCC;
    height: 15px;
    line-height: 15px;
    text-indent: 3px;
    text-transform: capitalize;
    z-index: -9999; 
}
optgroup { /* Change font style and text alignment */
    font-style:italic;
    text-align:right;
}

It has been noted by others that the markup is invalid and achieving consistency with native form controls across different browsers is quite a challenge.

In my view, opting for a JavaScript solution is likely the most efficient and secure approach, especially if you are willing to accept the additional page weight from including one or more libraries and/or plugins, and are okay with the fallback of the <select> not appearing as visually appealing.

Out of the various <select> replacement jQuery plugins that exist, I would highly suggest giving the Select 2 plugin a try. It offers a wide range of features, including the ability to add placeholder text to the control that can be customized to suit your needs.
