HTML, CSS and jQuery: Make a folding menu with animated effects

[Introduction]
The folding menu is a common interaction in modern web design element, which can effectively save page space while providing a better user experience. This article will introduce how to use HTML, CSS and jQuery to create a folding menu with animated effects, and provide specific code examples.

[Step 1: HTML structure]
First, we need to build a basic HTML structure. The following is a simple example:

<!DOCTYPE html>
<html>
<head>
    <title>折叠菜单示例</title>
    <link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
    <div class="menu">
        <div class="item">
            <h2 class="title">菜单项 1</h2>
            <ul class="sub-menu">
                <li>子菜单项 1</li>
                <li>子菜单项 2</li>
                <li>子菜单项 3</li>
            </ul>
        </div>
        <div class="item">
            <h2 class="title">菜单项 2</h2>
            <ul class="sub-menu">
                <li>子菜单项 1</li>
                <li>子菜单项 2</li>
                <li>子菜单项 3</li>
            </ul>
        </div>
        <!-- 更多菜单项... -->
    </div>

    <script src="jquery.min.js"></script>
    <script src="script.js"></script>
</body>
</html>

[Step 2: CSS Styles]
Next, add styles in the styles.css file. Design the appearance of the menu according to personal preferences. The following is a simple example:

.menu {
    width: 200px;
    background-color: #f0f0f0;
}

.item {
    padding: 10px;
    border-bottom: 1px solid #ccc;
    cursor: pointer;
}

.title {
    margin: 0;
}

.sub-menu {
    display: none;
    padding-left: 20px;
}

.sub-menu li {
    margin-bottom: 5px;
}

[Step 3: jQuery animation effects]
Finally, we use jQuery to achieve the menu's folding and expanding animation effects. Create a new file named script.js and add the following code:

$(document).ready(function() {    
    $('.item').click(function() {
        $(this).children('.sub-menu').slideToggle();
        $(this).toggleClass('active');
    });
});

Copy after login

The above code uses jQuery's .slideToggle() method to switch the display and hidden state of the submenu. At the same time, use the .toggleClass() method to add or remove a class named "active" for the clicked menu item. We can use CSS to define the style of the menu item when it is selected.

[Conclusion]
By using HTML, CSS and jQuery, we successfully created a folding menu with animated effects. When users click on menu items, submenus expand or collapse smoothly, providing a better user experience. This simple and practical menu can be applied to various web design and development projects to help improve user interaction experience.
