Plavajoče nalepke
Ustvarite čudovito preproste oznake obrazcev, ki lebdijo nad vašimi vnosnimi polji.
Primer
Zavijte par <input class="form-control">in <label>elementov, .form-floatingda omogočite plavajoče oznake z besedilnimi polji obrazca Bootstrap. Na placeholdervsakem je potreben A, <input>saj naša metoda lebdečih oznak CSS uporablja :placeholder-shownpsevdoelement. Upoštevajte tudi, da <input>mora biti prvi, da lahko uporabimo sorodni izbirnik (npr. ~).
<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>Ko je valueže določen, <label>se bo s samodejno prilagodil svojemu plavajočemu položaju.
<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>Tudi slogi preverjanja obrazcev delujejo po pričakovanjih.
<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
Privzeto bo <textarea>s z .form-controlenake višine kot <input>s.
<div class="form-floating">
<textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea"></textarea>
<label for="floatingTextarea">Comments</label>
</div>Če želite nastaviti višino po meri na vašem <textarea>, ne uporabite rowsatributa. Namesto tega nastavite eksplicitno height(v vrstici ali prek CSS po meri).
<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>Izbira
Razen .form-control, so plavajoče oznake na voljo samo na .form-selects. Delujejo na enak način, vendar bodo za razliko od <input>s vedno prikazali <label>v lebdečem stanju. Izbira z sizein multipleniso podprti.
<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>Postavitev
Ko delate z mrežnim sistemom Bootstrap, se prepričajte, da elemente obrazca postavite znotraj razredov stolpcev.

<div class="col-md">
