How Can I Customize the Select Dropdown Arrow Across Different Browsers?

Customizing Select Arrow Style

You are facing difficulties in modifying the appearance of a select element's arrow and making it consistent across browsers. Specifically, you are encountering issues in Firefox and Internet Explorer 9, where the arrow is not being replaced as desired.

To address this, it's crucial to understand the underlying browser differences. Chrome, Firefox, and IE9 handle custom styling of select elements' arrows in distinct ways.

Chrome and Safari:
These browsers have advanced support for styling the appearance of select arrows. Using CSS, you can define a custom background image and eliminate the default arrow.

Firefox:
Prior to version 35, Firefox does not natively support altering the appearance of the select arrow using CSS. As a result, the default arrow remains visible.

Internet Explorer 9:
IE9 is known to have certain limitations in styling select elements, including the inability to conceal the default arrow.

Solution:**

To achieve your desired result, you can incorporate browser-specific CSS properties:

.styled-select select {
    -moz-appearance:none; /* Firefox */
    -webkit-appearance:none; /* Safari and Chrome */
    appearance:none;
}

By applying these properties, you instruct Firefox to ignore its default appearance and use the custom styling defined in your CSS. Additionally, for IE9, you can utilize a workaround by using the background property to cover the default arrow with your own image.

Note:
As mentioned in the answer provided, Firefox up until version 35 does not natively support customizing the select arrow appearance. For legacy compatibility, consider checking the browser version and implementing alternative solutions, such as the one suggested in the mentioned jsfiddle.
