SourceEingangsgruppe
Erweitern Sie Formularsteuerelemente ganz einfach, indem Sie Text, Schaltflächen oder Schaltflächengruppen auf beiden Seiten von Texteingaben, benutzerdefinierten Auswahlen und benutzerdefinierten Dateieingaben hinzufügen.
Einfaches Beispiel
Platzieren Sie ein Add-On oder eine Schaltfläche auf beiden Seiten eines Eingangs. Sie können auch einen auf beiden Seiten eines Eingangs platzieren. Denken Sie daran, <label>
s außerhalb der Eingabegruppe zu platzieren.

<div class= "input-group-prepend" >
<span class= "input-group-text" > With textarea</span>
</div>
<textarea class= "form-control" aria-label= "With textarea" ></textarea>
</div>
Verpackung
Eingabegruppen werden standardmäßig per umbrochen flex-wrap: wrap
, um eine benutzerdefinierte Formularfeldvalidierung innerhalb einer Eingabegruppe zu ermöglichen. Sie können dies mit deaktivieren .flex-nowrap
.
Kopieren
<div class= "input-group flex-nowrap" >
<div class= "input-group-prepend" >
<span class= "input-group-text" id= "addon-wrapping" > @</span>
</div>
<input type= "text" class= "form-control" placeholder= "Username" aria-label= "Username" aria-describedby= "addon-wrapping" >
</div>
Dimensionierung
Fügen Sie die relativen Größenklassen des Formulars zu .input-group
sich selbst hinzu, und der Inhalt darin wird automatisch in der Größe angepasst – es ist nicht erforderlich, die Größenklassen der Formularsteuerelemente für jedes Element zu wiederholen.
Die Größenanpassung für die einzelnen Eingabegruppenelemente wird nicht unterstützt.

Barrierefreiheit
Screenreader werden Probleme mit Ihren Formularen haben, wenn Sie nicht für jede Eingabe eine Bezeichnung einfügen. Stellen Sie für diese Eingabegruppen sicher, dass alle zusätzlichen Bezeichnungen oder Funktionen an Hilfstechnologien weitergegeben werden.
Die genaue zu verwendende Technik ( <label>
mit der Klasse versteckte Elemente .sr-only
oder die Verwendung der Attribute aria-label
und aria-labelledby
, möglicherweise in Kombination mit aria-describedby
) und welche zusätzlichen Informationen übermittelt werden müssen, hängt von der genauen Art des Schnittstellen-Widgets ab, das Sie implementieren. Die Beispiele in diesem Abschnitt bieten einige Vorschläge für fallspezifische Ansätze.
