Grup d'entrada
Amplieu fàcilment els controls de formulari afegint text, botons o grups de botons a banda i banda de les entrades de text, seleccions personalitzades i entrades de fitxers personalitzades.
Col·loqueu un complement o un botó a banda i banda d'una entrada. També podeu col·locar-ne un als dos costats d'una entrada. No admetem diversos controls de formulari en un sol grup d'entrada i <label>
s han de sortir fora del grup d'entrada.

</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">
<div class="input-group-append">

</div>
</div>
<label for="basic-url">Your vanity URL</label>
<div class="input-group mb-3">

<div class="input-group-prepend">
<span class="input-group-text">With textarea</span>
</div>
<textarea class="form-control" aria-label="With textarea"></textarea>
</div>
Afegiu les classes de mida del formulari relatives al .input-group
mateix i el contingut es redimensionarà automàticament, sense necessitat de repetir les classes de mida del control del formulari a cada element.
No s'admet la mida dels elements individuals del grup d'entrada.

Els lectors de pantalla tindran problemes amb els vostres formularis si no incloeu una etiqueta per a cada entrada. Per a aquests grups d'entrada, assegureu-vos que qualsevol etiqueta o funcionalitat addicional es transmeti a les tecnologies d'assistència.
La tècnica exacta que s'ha d'utilitzar ( <label>
elements amagats amb la .sr-only
classe o ús dels atributs aria-label
i aria-labelledby
, possiblement en combinació amb aria-describedby
) i quina informació addicional caldrà transmetre variarà en funció del tipus exacte de giny d'interfície que esteu implementant. Els exemples d'aquesta secció proporcionen alguns enfocaments suggerits i específics per a casos.
