Bootstrap 5 is a powerful front-end framework that allows developers to create responsive and aesthetically pleasing web designs with ease. One of its useful components is the SelectPicker, which enhances standard select elements by providing a more customizable interface. This article will guide you on how to change the background color of a Bootstrap 5 SelectPicker and provide practical examples to illustrate the concept.
Understanding the Problem
The original issue you might encounter when trying to customize a SelectPicker's background color is that simply applying a CSS rule to the standard select element does not always affect the rendered SelectPicker. Here's a simplified version of how one might attempt to change the background color:
<select class="selectpicker" id="mySelect">
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
</select>
Customizing SelectPicker Background Color
To effectively change the background color of a Bootstrap 5 SelectPicker, you will need to employ some custom CSS. This customization typically involves targeting both the .selectpicker class and the dropdown menu itself. Below is the complete solution, including HTML and CSS.
Example Code
Here’s a simple implementation to change the SelectPicker's background color:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Bootstrap 5 SelectPicker Background Color</title>

<style>
/* Custom styles for the SelectPicker */
.bootstrap-select .dropdown-toggle {
background-color: #28a745; /* Change background color of toggle */
color: #fff; /* Change text color */
}
.bootstrap-select .dropdown-menu {
background-color: #f8f9fa; /* Change background color of dropdown */
}
.bootstrap-select .dropdown-menu .dropdown-item {
color: #333; /* Change dropdown items text color */
}
.bootstrap-select .dropdown-menu .dropdown-item:hover {
background-color: #007bff; /* Change background color on hover */
color: #fff; /* Change text color on hover */
}
</style>
</head>
<body>
<div class="container mt-5">
<h2>Select Example</h2>
<select class="selectpicker" id="mySelect" data-live-search="true">
