SourceВходна група
Лесно разширете контролите на формуляра, като добавите текст, бутони или групи бутони от двете страни на текстови входове, избори по избор и въвеждане на персонализирани файлове.
Поставете една добавка или бутон от двете страни на вход. Можете също така да поставите един от двете страни на входа. Не забравяйте да поставите <label>
s извън входната група.

Добавете относителните класове за оразмеряване на формуляра към .input-group
самия него и съдържанието в него автоматично ще се преоразмери – няма нужда да повтаряте класовете за размер на контрола на формуляра за всеки елемент.
Оразмеряването на отделните елементи на входната група не се поддържа.

Екранните четци ще имат проблеми с вашите формуляри, ако не включите етикет за всеки вход. За тези входни групи се уверете, че всеки допълнителен етикет или функционалност се предава на помощни технологии.
Точната техника, която ще се използва ( <label>
елементи, скрити с помощта на .sr-only
класа, или използване на атрибутите aria-label
и aria-labelledby
, евентуално в комбинация с aria-describedby
) и каква допълнителна информация ще трябва да бъде предадена ще варира в зависимост от точния тип интерфейсен модул, който прилагате. Примерите в този раздел предоставят няколко предложения, специфични за конкретни случаи подходи.
