インプットグループ

Input group

テキスト入力、カスタムセレクト、カスタムファイル入力の両側に、テキスト、ボタン、ボタングループを追加して、フォームコントロールを簡単に拡張できます。

基本的な例

片側または両端にボタン(またはアドオン)を配置できます。<label>は入力グループの外側に配置します。

@
@example.com
https://example.com/users/
Example help text goes outside the input group.
$ .00
@
With textarea
html
<div class="input-group mb-3">
  <span class="input-group-text" id="basic-addon1">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>

<div class="input-group mb-3">
  <input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
  <span class="input-group-text" id="basic-addon2">@example.com</span>
</div>

<div class="mb-3">
  <label for="basic-url" class="form-label">Your vanity URL</label>
  <div class="input-group">
    <span class="input-group-text" id="basic-addon3">https://example.com/users/</span>
    <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3 basic-addon4">
  </div>
  <div class="form-text" id="basic-addon4">Example help text goes outside the input group.</div>
</div>

<div class="input-group mb-3">
  <span class="input-group-text">$</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
  <span class="input-group-text">.00</span>
</div>

<div class="input-group mb-3">
  <input type="text" class="form-control" placeholder="Username" aria-label="Username">
  <span class="input-group-text">@</span>
  <input type="text" class="form-control" placeholder="Server" aria-label="Server">
</div>

<div class="input-group">
  <span class="input-group-text">With textarea</span>
  <textarea class="form-control" aria-label="With textarea"></textarea>
</div>

ラッピング

カスタムフォームフィールドの検証に対応するため、入力グループはデフォルトでflex-wrap: wrapで折り返します。これを無効にするには.flex-nowrapを使います。

@
html
<div class="input-group flex-nowrap">
  <span class="input-group-text" id="addon-wrapping">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="addon-wrapping">
</div>

サイズ調整

相対フォームサイズクラスを.input-group自体に追加すると、その中のコンテンツが自動的にリサイズされます。フォームコントロールのサイズクラスを各要素に繰り返し適用する必要はありません。

個々の入力グループ要素でのサイズ変更はサポートされていません。

Small
Default
Large
html
<div class="input-group input-group-sm mb-3">
  <span class="input-group-text" id="inputGroup-sizing-sm">Small</span>
  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-sm">
</div>

<div class="input-group mb-3">
  <span class="input-group-text" id="inputGroup-sizing-default">Default</span>
  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-default">
</div>

<div class="input-group input-group-lg">
  <span class="input-group-text" id="inputGroup-sizing-lg">Large</span>
  <input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-lg">
</div>

チェックボックスとラジオ

入力グループのアドオン内のチェックボックスやラジオオプションをテキストの代わりに配置します。入力の横に可視テキストがない場合は、.form-check-input.mt-0を追加することをお勧めします。

html
<div class="input-group mb-3">
  <div class="input-group-text">
    <input class="form-check-input mt-0" type="checkbox" value="" aria-label="Checkbox for following text input">
  </div>
  <input type="text" class="form-control" aria-label="Text input with checkbox">
</div>

<div class="input-group">
  <div class="input-group-text">
    <input class="form-check-input mt-0" type="radio" value="" aria-label="Radio button for following text input">
  </div>
  <input type="text" class="form-control" aria-label="Text input with radio button">
</div>

マルチプルインプット

複数の<input>が視覚的にサポートされています。validation stylesは単一の<input>を持つ入力グループに対してのみ利用可能です。

First and last name
html
<div class="input-group">
  <span class="input-group-text">First and last name</span>
  <input type="text" aria-label="First name" class="form-control">
  <input type="text" aria-label="Last name" class="form-control">
</div>

複数のアドオン

下記のように複数のボタン(またはアドオン)を並べることも可能です。

$ 0.00
$ 0.00
html
<div class="input-group mb-3">
  <span class="input-group-text">$</span>
  <span class="input-group-text">0.00</span>
  <input type="text" class="form-control" aria-label="Dollar amount (with dot and two decimal places)">
</div>

<div class="input-group">
  <input type="text" class="form-control" aria-label="Dollar amount (with dot and two decimal places)">
  <span class="input-group-text">$</span>
  <span class="input-group-text">0.00</span>
