Lebo zinazoelea
Unda lebo za fomu rahisi ambazo huelea juu ya sehemu zako za uingizaji.
Mfano
Funga jozi <input class="form-control">na <label>vipengee ndani .form-floatingili kuwezesha lebo zinazoelea kwa uga wa muundo wa maandishi wa Bootstrap. A placeholderinahitajika kwa kila moja <input>kwani mbinu yetu ya lebo zinazoelea za CSS pekee hutumia :placeholder-shownkipengele bandia. Pia kumbuka kuwa <input>lazima iwe kwanza ili tuweze kutumia kiteuzi cha kaka (kwa mfano, ~).
<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>Wakati kuna valuetayari imefafanuliwa, <label>s itarekebisha kiotomatiki kwa nafasi yao iliyoelea.
<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>Mitindo ya uthibitishaji wa fomu pia hufanya kazi inavyotarajiwa.
<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>Sehemu za maandishi
Kwa chaguo-msingi, <textarea>s with .form-controlitakuwa na urefu sawa na <input>s.
<div class="form-floating">
<textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea"></textarea>
<label for="floatingTextarea">Comments</label>
</div>Ili kuweka urefu maalum kwenye <textarea>, usitumie rowssifa. Badala yake, weka wazi height(iwe ndani ya mstari au kupitia CSS maalum).
<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>Inachagua
Zaidi ya .form-control, lebo zinazoelea zinapatikana tu kwenye .form-selects. Zinafanya kazi kwa njia sawa, lakini tofauti na <input>s, zitaonyesha kila wakati <label>katika hali yake ya kuelea. Inachagua sizena multiplehaitumiki.
<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>Mpangilio
Unapofanya kazi na mfumo wa gridi ya Bootstrap, hakikisha kuweka vipengele vya fomu ndani ya madarasa ya safu.
