Show Selected Option In Bootstrap Dropdown List Menu

Dropdown menus are a common feature on websites and applications, providing users with a convenient way to navigate through various options. In this article, we'll focus on how to showcase the selected option in a Bootstrap dropdown list menu. This is a handy feature that can enhance user experience by visually highlighting the current selection.

To achieve this in Bootstrap, we can use a combination of HTML, CSS, and JavaScript. Let's walk through the process step by step.

### Step 1: Setting Up the HTML
Start by creating a basic HTML structure that includes a Bootstrap dropdown menu. You can use the following code as a template:

Html

<div class="dropdown">
  <button class="btn btn-primary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-expanded="false">
    Select an option
  </button>
  <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
    <a class="dropdown-item" href="#">Option 1</a>
    <a class="dropdown-item" href="#">Option 2</a>
    <a class="dropdown-item" href="#">Option 3</a>
  </div>
</div>

### Step 2: Adding JavaScript Functionality
Next, we need to write a JavaScript function that updates the dropdown button text based on the selected option. Below is a simple script that achieves this:

Javascript

$('.dropdown-item').click(function(){
  var selectedOption = $(this).text();
  $('.dropdown-toggle').text(selectedOption);
});

### Step 3: Styling with CSS
To enhance the visual presentation of the selected option, you can add some CSS styles. Here's an example to change the background color of the selected item:

Css

.dropdown-item.active {
  background-color: #f8d7da; /* Red background color for illustration purposes */
}

### Step 4: Implementation
Now that you have the necessary code snippets, you can integrate them into your project. Ensure that you have included the Bootstrap CSS and JavaScript files in your project for proper functionality.

### Tips for Customizing
- You can modify the CSS styles to customize the appearance of the selected option further.
- Extend the JavaScript functionality to perform additional actions when an option is selected, such as triggering an event or updating other elements on the page.

By following these steps, you can enhance the interactivity of your Bootstrap dropdown menu by displaying the selected option prominently. This small but effective feature can improve the usability of your website or application, making it easier for users to navigate through the available choices.

Feel free to experiment with different styling options and JavaScript enhancements to tailor the dropdown menu behavior to your specific requirements. With a bit of creativity and technical know-how, you can create a polished user interface that engages and delights your audience.
