Lipéid ar snámh
Cruthaigh lipéid fhoirm álainne simplí a shnámhann thar do réimsí ionchuir.
Sampla
Wrap péire de <input class="form-control">
agus <label>
eilimintí isteach .form-floating
chun lipéid ar snámh a chumasú le réimsí foirmeacha téacs Bootstrap. Tá A placeholder
ag teastáil ar gach ceann <input>
de bharr go n-úsáideann ár modh lipéadaithe CSS amháin an :placeholder-shown
bréige. Tabhair faoi deara freisin nach <input>
mór an chéad teacht chun cinn ionas gur féidir linn úsáid a bhaint as roghnóir siblín (m.sh., ~
).
<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>
Nuair atá s value
sainithe ann cheana féin, <label>
coigeartóidh s go huathoibríoch go dtí a suíomh ar snámh.
<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>
Oibríonn stíleanna bailíochtaithe foirmeacha freisin de réir mar a bheifí ag súil leis.
<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>
Réimsí téacs
De réir réamhshocraithe, beidh <textarea>
s leis .form-control
an airde chéanna le <input>
s.
<div class="form-floating">
<textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea"></textarea>
<label for="floatingTextarea">Comments</label>
</div>
Chun airde saincheaptha a shocrú ar do <textarea>
, ná húsáid an rows
tréith. Ina áit sin, socraigh sainráite height
(ceachtar inlíne nó trí CSS saincheaptha).
<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>
Roghnaíonn
Seachas .form-control
, níl lipéid ar snámh ar fáil ach ar .form-select
s. Oibríonn siad ar an mbealach céanna, ach murab ionann agus <input>
s, beidh siad a thaispeáint i gcónaí ar an <label>
ina staid snámh. Roghnaíonn size
agus multiple
ní thacaítear leo.
<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>
Leagan Amach
Agus tú ag obair le córas greille Bootstrap, bí cinnte go gcuirfí gnéithe foirme laistigh de ranganna colún.
<div class="row g-2">
<div class="col-md">
<div class="form-floating">
<input type="email" class="form-control" id="floatingInputGrid" placeholder="[email protected]" value="[email protected]">
<label for="floatingInputGrid">Email address</label>
</div>
</div>
<div class="col-md">
<div class="form-floating">
<select class="form-select" id="floatingSelectGrid" 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="floatingSelectGrid">Works with selects</label>
