Bài 34: Range trong Bootstrap 5

Input Group

Class .input-group là một container nâng cao input bằng cách thêm icon, văn bản hoặc một nút bấm ở phía trước hay phía sau trường nhập dưới dạng “help text” - văn bản trợ giúp.

Để định dạng kiểu text trợ giúp, dùng class .input-group-text:

Code mẫu:

<form>
<div class="input-group">
<span class="input-group-text">@</span>
<input type="text" class="form-control" placeholder="Username">
</div>

<div class="input-group">
<input type="text" class="form-control" placeholder="Your Email">
<span class="input-group-text">@example.com</span>
</div>
</form>

Ví dụ:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">
  <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>

<div class="container mt-3">
  <h2>Input Group cho Sinitc.com</h2>
 
  <form action="/action_page.php">
    <div class="input-group mb-3">
      <span class="input-group-text">@</span>
      <input type="text" class="form-control" placeholder="Tên người dùng" name="usrname">
    </div>

    <div class="input-group mb-3">
      <input type="text" class="form-control" placeholder="Địa chỉ email của bạn" name="email">
      <span class="input-group-text">@example.com</span>
    </div>
    
    <button type="submit" class="btn btn-primary">Đăng ký</button>
  </form>
</div>

</body>
</html>

Kích thước Input Group

Dùng class .input-group-sm cho các nhóm input nhỏ và .input-group-lg cho các nhóm input lớn. Code mẫu:

<div class="input-group mb-3 input-group-sm">
<span class="input-group-text">Small</span>
<input type="text" class="form-control">
</div>

<div class="input-group mb-3">
<span class="input-group-text">Default</span>
<input type="text" class="form-control">
</div>

<div class="input-group mb-3 input-group-lg">
<span class="input-group-text">Large</span>
<input type="text" class="form-control">
</div>

Ví dụ:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">
  <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>

<div class="container mt-3">
  <h2>Kích thước nhóm Input</h2>
  
  <div class="input-group input-group-sm mb-3">
    <span class="input-group-text">Nhỏ</span>
    <input type="text" class="form-control">
  </div>
  <div class="input-group mb-3">
    <span class="input-group-text">Mặc định</span>
    <input type="text" class="form-control">
  </div>
  <div class="input-group input-group-lg mb-3">
    <span class="input-group-text">Lớn</span>
    <input type="text" class="form-control">
  </div>
</div>

</body>
</html>

Nhiều Input và Helper

Thêm nhiều input và addon như code mẫu:

<!-- Multiple inputs -->
<div class="input-group mb-3">
<span class="input-group-text">Person</span>
<input type="text" class="form-control" placeholder="First Name">
<input type="text" class="form-control" placeholder="Last Name">
</div>

<!-- Multiple addons / help text -->
<div class="input-group mb-3">
<span class="input-group-text">One</span>
<span class="input-group-text">Two</span>
<span class="input-group-text">Three</span>
<input type="text" class="form-control">
</div>

Ví dụ:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">
  <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>

    <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
  
  <div class="container mt-3">
    <p>Thêm nhiều input hoặc addon:</p>
    
    <!-- Multiple inputs -->
    <div class="input-group mb-3">
      <span class="input-group-text">Họ tên</span>
      <input type="text" class="form-control" placeholder="Tên">
      <input type="text" class="form-control" placeholder="Họ">
    </div>
  
    <!-- Multiple addons / help text -->

Input Group với checkbox và radio

Bạn cũng có thể dùng các ô tích hoặc radio button thay cho text. Code mẫu:

<div class="input-group mb-3">
<div class="input-group-text">
<input type="checkbox">
</div>
<input type="text" class="form-control" placeholder="Some text">
</div>

<div class="input-group mb-3">
<div class="input-group-text">
<input type="radio">
</div>
<input type="text" class="form-control" placeholder="Some text">
</div>

Ví dụ:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">
  <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>

<div class="container mt-3">
 <h2> Chọn trang bạn thích </h2> 
  <!-- Multiple inputs -->
  <div class="input-group mb-3">
    <div class="input-group-text">
      <input type="checkbox">
    </div>
    <input type="text" class="form-control" placeholder="Sinitc">
  </div>
  <div class="input-group mb-3">
    <div class="input-group-text">
      <input type="radio">
    </div>
    <input type="text" class="form-control" placeholder="Sinitc1">
  </div>
</div>

</body>
</html>

Các nút Input Group

Code mẫu:

<div class="input-group mb-3">
<button class="btn btn-outline-primary" type="button">Basic Button</button>
<input type="text" class="form-control" placeholder="Some text">
</div>

<div class="input-group mb-3">
<input type="text" class="form-control" placeholder="Search">
<button class="btn btn-success" type="submit">Go</button>
</div>

<div class="input-group mb-3">
<input type="text" class="form-control" placeholder="Something clever..">
<button class="btn btn-primary" type="button">OK</button>
<button class="btn btn-danger" type="button">Cancel</button>
</div>

Ví dụ:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">
  <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>

<div class="container mt-3">
  <h3>Nút bấm nhóm input</h3>
  
  <div class="input-group mb-3 mt-3">
    <button class="btn btn-outline-primary" type="button">Nút bấm cơ bản</button>
    <input type="text" class="form-control" placeholder="Truy cập Sinitc.com">
  </div>

  <div class="input-group mb-3">

  </div>

  <div class="input-group mb-3">
    <input type="text" class="form-control" placeholder="Xem...">
    <button class="btn btn-primary" type="button">OK</button> 
    <button class="btn btn-danger" type="button">Cancel</button> 
  </div>
</div>

</body>
</html>

Input Group với nút bấm thả xuống

Thêm một nút bấm thả xuống trong nhóm input. Lưu ý rằng bạn không cần “wrapper” .dropdown như bình thường.

Code mẫu:

<div class="input-group mt-3 mb-3">
  <button type="button" class="btn btn-primary dropdown-toggle" data-bs-toggle="dropdown">
    Dropdown button
  </button>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Link 1</a></li>
    <li><a class="dropdown-item" href="#">Link 2</a></li>
    <li><a class="dropdown-item" href="#">Link 3</a></li>
  </ul>
  <input type="text" class="form-control" placeholder="Username">
</div>

Ví dụ:

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">
  <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>

<div class="container mt-3">
    
  <div class="input-group mt-3 mb-3">
    <button type="button" class="btn btn-primary dropdown-toggle" data-bs-toggle="dropdown">
      Nút bấm thả xuống
    </button>
    <ul class="dropdown-menu">
      <li><a class="dropdown-item" href="#">Link Sinitc 1</a></li>
      <li><a class="dropdown-item" href="#">Link 2</a></li>
      <li><a class="dropdown-item" href="#">Link 3</a></li>
    </ul>
    <input type="text" class="form-control" placeholder="Sinitc.com">
  </div>
</div>
