Add some styling to the dropdown option element using CSS

My dropdown menu appears like this:-

<select id="fruits">
    <option value="-1">Select</option>
    <option value="1">Banana</option>
    <option value="2">Apple</option>
    <option value="3">Grapes</option>
</select>

I want to customize the style of one of the options using jQuery's .css property, but it is not behaving as expected in IE11 or Firefox. Here is my jQuery code snippet:-

$("#fruits").change(function () {
    $(this).css("background-color", "transparent");
    $(this).find('option').css("background-color", "transparent");
    var selectedVal = $(this).find('option:selected');
    if (selectedVal != "-1")
    {
       console.log("Before->" + $(this).find('option:selected').css("background-color"));
       $(this).find('option:selected').css("background-color", "#BEF781");
       console.log("After->" + $(this).find('option:selected').css("background-color"));
    }
});

The issue with this code is that although it updates the DOM (as confirmed through developer tools and Firebug), when trying to retrieve the value of background-color, it returns the old value rgb(51, 153, 255) instead of the updated rgb(190, 247, 129), and it doesn't update the color in IE11. While this code previously worked in IE7, I am now aiming for it to function correctly in IE11. Any suggestions on what I should do?

P.S. - This functionality works smoothly in JSFiddle, which has been verified. However, I need it to work specifically in IE11.

Answer №1

Customizing the appearance of select boxes and their child options presents challenges due to varying levels of support across different browsers. For example, Firefox allows font styling within options while Chrome permits styling of the entire list but not individual options (if memory serves me right). Check out this resource for further insights. A workaround involves styling alternate elements to mimic a select box and using JavaScript to replicate its functionality.

Answer №2

To ensure a consistent look and feel across different browsers, my suggestion would be to use the jQuery UI selectMenu widget. Implementation is straightforward, as outlined below:

Incorporate the following code into your HTML (similar to what you had before):

    <select id="fruits" style="width: 200px;">
        <option value="-1">Select</option>
        <option value="1">Banana</option>
        <option value="2">Apple</option>
        <option value="3">Grapes</option>
    </select>

Add the following snippet to your header:

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>

Lastly, include this custom script in your code:

$(document).ready(function () {
    $("#fruits").selectmenu({
        select: function (event, ui) {

            // Set all list items to transparent.
            $(".ui-selectmenu-menu li.ui-menu-item").css("background-color", "transparent");

            // Highlight the SELECTED list item in green.
            $(".ui-selectmenu-menu li.ui-menu-item:nth-child(" + (ui.item.index + 1) + ")").css("background-color", "#BEF781");
        }
    });
});
