Label ngambang
Gawe label formulir sing gampang banget sing ngambang ing kolom input sampeyan.
Tuladha
Bungkus pasangan <input class="form-control">
lan <label>
unsur .form-floating
kanggo ngaktifake label ngambang nganggo kolom formulir teks Bootstrap. A placeholder
dibutuhake ing saben <input>
minangka metode label ngambang mung CSS nggunakake :placeholder-shown
unsur pseudo. Uga elinga manawa <input>
kudu luwih dhisik supaya kita bisa nggunakake pamilih sedulur (contone, ~
).
<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>
Nalika ana sing value
wis ditetepake, <label>
s bakal otomatis nyetel posisi floated sing.
<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>

<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>
Area Teks
Kanthi gawan, <textarea>
s karo .form-control
bakal dhuwur padha <input>
s.
<div class="form-floating">
<textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea"></textarea>
<label for="floatingTextarea">Comments</label>
</div>
Kanggo nyetel dhuwur khusus ing <textarea>
, aja nggunakake rows
atribut kasebut. Nanging, atur eksplisit height
(ing baris utawa liwat CSS khusus).
<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>

, label ngambang mung kasedhiya ing .form-select
s. Padha bisa ing cara sing padha, nanging ora kaya <input>
s, padha bakal tansah nuduhake ing <label>
negara floated sawijining. Milih karo size
lan multiple
ora didhukung.
