Plutajuće etikete

Kreirajte prelijepo jednostavne oznake obrazaca koje lebde iznad vaših polja za unos.

Primjer

Umotajte par elemenata i <input class="form-control">da biste omogućili plutajuće naljepnice s Bootstrapovim tekstualnim poljima obrasca. A je potrebno na svakom jer naša metoda plutajućih oznaka samo za CSS koristi pseudoelement. Također imajte na umu da mora biti prvi kako bismo mogli koristiti bratski selektor (npr. ).<label>.form-floatingplaceholder<input>:placeholder-shown<input>~

E-mail adresa

Lozinka

html

<div class="form-floating mb-3">
  <input type="email" class="form-control" id="floatingInput" placeholder="[email protected]">
  <label for="floatingInput">Email address</label>
</div>
<div class="form-floating">
  <input type="password" class="form-control" id="floatingPassword" placeholder="Password">
  <label for="floatingPassword">Password</label>
</div>

Kada postoji valueveć definiran, <label>s će se automatski prilagoditi svom plutajućem položaju.

html

<form class="form-floating">
  <input type="email" class="form-control" id="floatingInputValue" placeholder="[email protected]" value="[email protected]">
  <label for="floatingInputValue">Input with value</label>
</form>

Stilovi provjere valjanosti obrazaca također rade kako se očekuje.

html

<form class="form-floating">
  <input type="email" class="form-control is-invalid" id="floatingInputInvalid" placeholder="[email protected]" value="[email protected]">
  <label for="floatingInputInvalid">Invalid input</label>
</form>

Textareas

Podrazumevano, <textarea>s sa .form-controlće biti iste visine kao <input>s.

Komentari

html

<div class="form-floating">
  <textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea"></textarea>
  <label for="floatingTextarea">Comments</label>
</div>

Da biste postavili prilagođenu visinu na vašem <textarea>, nemojte koristiti rowsatribut. Umjesto toga, postavite eksplicitni height(bilo umetnuti ili putem prilagođenog CSS-a).

Komentari

html

<div class="form-floating">
  <textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea2" style="height: 100px"></textarea>
  <label for="floatingTextarea2">Comments</label>
</div>

Odabire

Osim .form-control, plutajuće naljepnice dostupne su samo na .form-selects. Oni rade na isti način, ali za razliku od <input>s, uvijek će prikazivati <label>u plutajućem stanju. Odabire sa sizei multiplenisu podržani.

Radi sa odabranima

html

<div class="form-floating">
  <select class="form-select" id="floatingSelect" aria-label="Floating label select example">
    <option selected>Open this select menu</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
  </select>
  <label for="floatingSelect">Works with selects</label>
</div>

Čisti tekst samo za čitanje

Plutajuće naljepnice također podržavaju .form-control-plaintext, što može biti od pomoći za prebacivanje sa vrijednosti koja se može uređivati <input>na vrijednost otvorenog teksta bez utjecaja na izgled stranice.

Prazan unos

Unesite vrijednost

html

<div class="form-floating mb-3">
  <input type="email" readonly class="form-control-plaintext" id="floatingEmptyPlaintextInput" placeholder="[email protected]">
  <label for="floatingEmptyPlaintextInput">Empty input</label>
</div>
<div class="form-floating mb-3">
  <input type="email" readonly class="form-control-plaintext" id="floatingPlaintextInput" placeholder="[email protected]" value="[email protected]">
  <label for="floatingPlaintextInput">Input with value</label>
</div>

Grupe unosa

Plutajuće naljepnice također podržavaju .input-group.

Korisničko ime

html

<div class="input-group mb-3">
  <span class="input-group-text">@</span>
  <div class="form-floating">
    <input type="text" class="form-control" id="floatingInputGroup1" placeholder="Username">
    <label for="floatingInputGroup1">Username</label>
  </div>
</div>

Kada koristite .input-groupi .form-floatingzajedno s provjerom valjanosti obrasca, -feedbacktreba postaviti izvan .form-floating, ali unutar .input-group. To znači da će povratne informacije morati biti prikazane pomoću javascripta.

Korisničko ime

Molimo odaberite korisničko ime.

html

<div class="input-group has-validation">
  <span class="input-group-text">@</span>
  <div class="form-floating is-invalid">
    <input type="text" class="form-control is-invalid" id="floatingInputGroup2" placeholder="Username" required>
    <label for="floatingInputGroup2">Username</label>
  </div>
  <div class="invalid-feedback">
    Please choose a username.
  </div>
</div>

Layout

Kada radite sa Bootstrap grid sistemom, obavezno postavite elemente obrasca unutar klasa stupaca.
