SourceГрупа уноса
Лако проширите контроле обрасца додавањем текста, дугмади или група дугмади са обе стране текстуалних уноса, прилагођених одабира и прилагођених уноса датотека.
Основни пример
Поставите један додатак или дугме са обе стране улаза. Такође можете поставити један на обе стране улаза. Не заборавите да поставите <label>
с ван групе за унос.

<span class= "input-group-text" > With textarea</span>
</div>
<textarea class= "form-control" aria-label= "With textarea" ></textarea>
</div>
Враппинг
Групе уноса се подразумевано преламају преко flex-wrap: wrap
да би се прилагодила валидација поља обрасца у оквиру групе за унос. Ово можете да онемогућите са .flex-nowrap
.
Копирај
<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>
Одређивање величине
Додајте релативне класе величине обрасца у .input-group
саму себе и садржај унутар ће аутоматски променити величину – нема потребе за понављањем класа величине контроле обрасца на сваком елементу.
Одређивање величине појединачних елемената групе уноса није подржано.

Поља за потврду и радио
Поставите било које поље за потврду или радио опцију у додатак групе за унос уместо текста.

подржано визуелно, стилови валидације су доступни само за групе уноса са једним <input>

Приступачност
Читачи екрана ће имати проблема са вашим обрасцима ако не укључите ознаку за сваки унос. За ове групе уноса, обезбедите да се свака додатна ознака или функционалност пренесе на помоћне технологије.
Тачна техника која ће се користити ( <label>
елементи скривени коришћењем .sr-only
класе, или употреба атрибута aria-label
и aria-labelledby
, могуће у комбинацији са aria-describedby
) и које додатне информације ће требати да се пренесу варираће у зависности од тачног типа виџета интерфејса који имплементирате. Примери у овом одељку пружају неколико предложених приступа специфичних за случај.
