Ulazna grupa

Jednostavno proširite kontrole obrazaca dodavanjem teksta, gumba ili grupa gumba s obje strane tekstualnih unosa, prilagođenih odabira i prilagođenih unosa datoteka.

Osnovni primjer

Postavite jedan dodatak ili gumb s obje strane ulaza. Također možete postaviti jedan s obje strane ulaza. Ne zaboravite staviti <label>s izvan ulazne grupe.

https://example.com/users/

  <textarea class="form-control" aria-label="With textarea"></textarea>
</div>

Zamatanje

Grupe unosa prelamaju se prema zadanim postavkama preko flex-wrap: wrapkako bi se prilagodila provjera valjanosti polja obrasca unutar ulazne grupe. Ovo možete onemogućiti pomoću .flex-nowrap.

@ 
<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>

Dimenzioniranje

Dodajte relativne klase veličine obrasca samom .input-groupsebi i sadržaj unutar će automatski promijeniti veličinu—nema potrebe za ponavljanjem klasa veličine kontrole obrasca na svakom elementu.

Određivanje veličine pojedinačnih elemenata ulazne grupe nije podržano.

Polje za potvrdu i radio

Postavite bilo koji potvrdni okvir ili radio opciju unutar dodatka ulazne grupe umjesto teksta.

<div class="input-group mb-3">
  <div class="input-group-prepend">
    <div class="input-group-text">

  </div>
  <input type="text" class="form-control" aria-label="Text input with radio button">
</div>

Višestruki ulazi

Iako je više <input>s vizualno podržano, stilovi provjere valjanosti dostupni su samo za grupe unosa s jednim <input>.

Pristupačnost

Osigurajte da sve kontrole obrasca imaju odgovarajuće dostupno ime kako bi se njihova svrha mogla prenijeti korisnicima pomoćnih tehnologija. Najjednostavniji način da to postignete je korištenje <label>elementa ili – u slučaju gumba – uključivanje dovoljno opisnog teksta kao dijela <button>...</button>sadržaja.

Za situacije u kojima nije moguće uključiti vidljiv <label>ili prikladan tekstualni sadržaj, postoje alternativni načini pružanja dostupnog naziva, kao što su:

  • <label>elementi skriveni pomoću .sr-onlyklase
  • Pokazivanje na postojeći element koji može djelovati kao oznaka pomoćuaria-labelledby
  • Pružanje titleatributa
  • Eksplicitno postavljanje pristupačnog imena na element pomoćuaria-label

Ako ništa od toga nije prisutno, pomoćne tehnologije mogu pribjeći korištenju placeholderatributa kao zamjene za dostupno ime na <input>i <textarea>elementima. Primjeri u ovom odjeljku daju nekoliko predloženih pristupa specifičnih za slučaj.

Iako će korištenje vizualno skrivenog sadržaja ( .sr-only, aria-label, pa čak i placeholdersadržaja, koji nestaje nakon što polje obrasca ima sadržaj) koristiti korisnicima pomoćne tehnologije, nedostatak vidljivog teksta naljepnice još uvijek može biti problematičan za određene korisnike. Neki oblik vidljive oznake općenito je najbolji pristup, kako za pristupačnost tako i za upotrebljivost.
