Leagan Amach
Bíodh struchtúr éigin ar d’fhoirmeacha – ó inlíne go feidhmiúcháin chothrománach go greille saincheaptha – lenár roghanna leagan amach foirmeacha.
Foirmeacha
<form>
Ba cheart go mbeadh eilimint ag gach grúpa de réimsí foirmeacha . Ní sholáthraíonn Bootstrap aon stíliú réamhshocraithe don <form>
eilimint, ach tá roinnt gnéithe brabhsálaí cumhachtacha a chuirtear ar fáil de réir réamhshocraithe.
- Nua ar fhoirmeacha brabhsálaí? Smaoinigh ar na doiciméid fhoirm MDN a athbhreithniú le haghaidh forbhreathnú agus liosta iomlán de na tréithe atá ar fáil.
<button>
s laistigh de<form>
réamhshocrútype="submit"
, mar sin déan iarracht a bheith sainiúil agustype
.- Is féidir leat gach eilimint fhoirm laistigh d'fhoirm a dhíchumasú leis an
disabled
tréith ar an<form>
.
Ós rud é go bhfuil feidhm ag Bootstrap display: block
agus maidir width: 100%
lenár rialuithe foirme go léir nach mór, cruachálfar foirmeacha go hingearach de réir réamhshocraithe. Is féidir ranganna breise a úsáid chun an leagan amach seo a athrú de réir foirme.
Fóntais
Is iad fóntais corrlaigh an bealach is éasca chun roinnt struchtúr a chur le foirmeacha. Soláthraíonn siad grúpáil bhunúsach de lipéid, rialuithe, téacs foirme roghnach, agus teachtaireachtaí bailíochtaithe foirmeacha. Molaimid cloí le margin-bottom
fóntais, agus úsáid a bhaint as treo amháin ar fud an fhoirm le haghaidh comhsheasmhachta.
Ná bíodh drogall ort d’fhoirmeacha a chur le chéile mar is mian leat, le <fieldset>
s, <div>
s, nó beagnach aon eilimint eile.
<div class="mb-3">
<label for="formGroupExampleInput" class="form-label">Example label</label>
<input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input placeholder">
</div>
<div class="mb-3">
<label for="formGroupExampleInput2" class="form-label">Another label</label>
<input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input placeholder">
</div>
Foirm greille
Is féidir foirmeacha níos casta a thógáil ag baint úsáide as ár ranganna greille. Úsáid iad seo le haghaidh leagan amach foirmeacha a éilíonn colúin iolracha, leithid éagsúil, agus roghanna ailínithe breise. Éilíonn sé $enable-grid-classes
go mbeidh an athróg Sass cumasaithe (ar siúl de réir réamhshocraithe).
<div class="row">
<div class="col">
<input type="text" class="form-control" placeholder="First name" aria-label="First name">
</div>
<div class="col">
<input type="text" class="form-control" placeholder="Last name" aria-label="Last name">
</div>
</div>
gáitéir
Trí ranganna mionathraithe gáitéir a chur leis , is féidir leat smacht a bheith agat ar leithead an gháitéir chomh maith leis an treo inlíne mar bhloc. Éilíonn sé freisin an $enable-grid-classes
athróg Sass a chumasú (ar aghaidh de réir réamhshocraithe).
<div class="row g-3">
<div class="col">
<input type="text" class="form-control" placeholder="First name" aria-label="First name">
</div>
<div class="col">
<input type="text" class="form-control" placeholder="Last name" aria-label="Last name">
</div>
</div>
Is féidir leagan amach níos casta a chruthú leis an gcóras greille freisin.

Foirm chothrománach
Cruthaigh foirmeacha cothrománacha leis an eangach tríd an .row
rang a chur le grúpaí foirme agus na .col-*-*
ranganna a úsáid chun leithead do lipéid agus do rialtáin a shonrú. Bí cinnte go gcuirfidh .col-form-label
tú le do <label>
chuid s freisin ionas go mbeidh siad dírithe go hingearach leis na rialuithe foirme a bhaineann leo.
Uaireanta, b'fhéidir go mbeadh ort úsáid a bhaint as fóntais corrlaigh nó stuála chun an ailíniú foirfe sin a theastaíonn uait a chruthú. Mar shampla, bhaineamar an padding-top
lipéad ar ár lipéad ionchuir raidió cruachta chun bunlíne an téacs a ailíniú níos fearr.

Méid lipéad foirme cothrománach
Bí cinnte a úsáid .col-form-label-sm
nó .col-form-label-lg
ar do chuid <label>
nó <legend>
s a leanúint i gceart méid .form-control-lg
agus .form-control-sm
.
<div class="row mb-3">
<label for="colFormLabelSm" class="col-sm-2 col-form-label col-form-label-sm">Email</label>

</div>
Méid an cholúin
Mar a léiríodh sna samplaí roimhe seo, ligeann ár gcóras eangaí duit aon líon .col
s a chur laistigh de .row
. Roinnfidh siad an leithead atá ar fáil go cothrom eatarthu. Is féidir leat fo-thacar de do cholúin a phiocadh freisin chun níos mó spáis nó níos lú a ghlacadh, agus na .col
s eile a roinnt go cothrom leis an gcuid eile, le haicmí colúin ar leith mar .col-sm-7
.
<div class="row g-3">
<div class="col-sm-7">
<input type="text" class="form-control" placeholder="City" aria-label="City">
</div>
<div class="col-sm">
<input type="text" class="form-control" placeholder="State" aria-label="State">
</div>
<div class="col-sm">
<input type="text" class="form-control" placeholder="Zip" aria-label="Zip">
</div>
</div>
Uathmhéadú
Úsáideann an sampla thíos áirgiúlacht flexbox chun an t-ábhar a lárú go hingearach agus athraíonn .col
sé .col-auto
é ionas nach nglacfaidh do cholúin ach an oiread spáis agus is gá. Cuir ar bhealach eile, na méideanna colún féin bunaithe ar an ábhar.
<form class="row gy-2 gx-3 align-items-center">

<div class="col-auto">

</div>
<div class="col-auto">
<button type="submit" class="btn btn-primary">Submit</button>

</form>
Is féidir leat é sin a athmhúnlú arís le ranganna colúin a bhaineann go sonrach le méid.

Foirmeacha inlíne
Bain úsáid as na .row-cols-*
ranganna chun leagan amach cothrománach sofhreagrach a chruthú. Trí ranganna modhnóirí gutter a chur leis , beidh gáitéir againn i dtreonna cothrománacha agus ingearacha. Ar na hamharcphointí cúnga soghluaiste, .col-12
cabhraíonn na rialtáin fhoirmeacha agus go leor eile a chruachadh. Ailíníonn na .align-items-center
heilimintí foirm go dtí an lár, ag déanamh an .form-checkbox
ailínithe i gceart.
