Customizing Select Box Options Width and Overflow
In web development, selecting options from a drop-down list can be a valuable feature. However, sometimes the width of the options may exceed the width of the select box, creating an aesthetic issue. To address this, we explore a solution that sets the width of the options to match the select box and ensures text overflow is handled gracefully.
Understanding the Challenge
As illustrated in the attached image, when the width of the options exceeds the width of the select box, it can create a visually unappealing layout. Our goal is to align the widths of the options with that of the select box and implement text ellipsis for long options.
HTML and CSS Approaches
Initially, we attempted a solution solely using CSS. However, our efforts proved futile. Subsequently, we discovered a simple yet effective JavaScript code that elegantly addresses the issue.
JavaScript Solution
The provided JavaScript function, shortString() loops through elements matching a specified selector ('.short') and trims any text that exceeds the specified data-limit attribute. This ensures that the text is encapsulated within the desired width, with an ellipsis denoting any truncation.
Implementation
To implement this solution, simply include the JavaScript code and add the 'data-limit' attribute to options in your HTML. The following snippet combines the code and HTML markup for your reference:
<code class="js">function shortString(selector) {
// ... (function logic omitted for brevity)
}
window.onload = function() {
shortString('.short');
};</code>
<code class="html"><select name="select" id="select"> <option class='short' data-limit='37' value="Select your University">Select your University</option> <option class='short' data-limit='37' value="Bangladesh University of Engineering and Technology">Bangladesh University of Engineering and Technology</option> <option class='short' data-limit='37' value="Mawlana Bhashani Science and Technology University">Mawlana Bhashani Science and Technology University</option> </select></code>
Conclusion
In conclusion, by leveraging JavaScript, we can customize the width of select box options and prevent text overflow issues. The provided code allows for a visually pleasing and user-friendly dropdown list, regardless of the length of the options.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
