Isakhiwo
Nikeza amafomu akho ukwakheka okuthile—kusuka emgqeni kuya kokuvundlile ukuya ekusetshenzisweni kwegridi yangokwezifiso—ngezinketho zethu zesakhiwo sefomu.
Amafomu
Iqembu ngalinye lezinkambu zefomu kufanele lihlale endaweni ethile <form>
. I-Bootstrap ayihlinzeki ngesitayela esizenzakalelayo sesici <form>
, kodwa kunezici ezithile zesiphequluli ezinamandla ezinikezwa ngokuzenzakalelayo.
- Umusha kumafomu esiphequluli? Cabangela ukubuyekeza amadokhumenti efomu le-MDN ukuze uthole umbono kanye nohlu oluphelele lwezibaluli ezitholakalayo.
<button>
s ngaphakathi<form>
kokuzenzakalelayo kokuthitype="submit"
, ngakho-ke lwela ukucacisa futhi njalo ufake i-type
.- Ungakwazi ukukhubaza yonke into yefomu ngaphakathi kwefomu
disabled
ngesibaluli esiku-<form>
.
Njengoba i-Bootstrap isebenza display: block
futhi width: 100%
cishe kuzo zonke izilawuli zethu zefomu, amafomu azonqwabeleka ngokuzenzakalelayo. Amakilasi engeziwe angasetshenziswa ukushintsha lesi sakhiwo ngokwefomu ngalinye.
Izinsiza
Izinsiza ze-margin ziyindlela elula yokwengeza isakhiwo kumafomu. Bahlinzeka ngokuhlanganisa okuyisisekelo kwamalebula, izilawuli, umbhalo wefomu ozikhethela wona, kanye nemiyalezo yokuqinisekisa yefomu. Sincoma ukuthi unamathele margin-bottom
kuzinsiza, futhi usebenzise isiqondiso esisodwa kulo lonke ifomu ukuze uthole ukuvumelana.
Zizwe ukhululekile ukwakha amafomu akho ngendlela othanda ngayo, nge- <fieldset>
s, <div>
s, nanoma iyiphi enye into.
<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>
Igridi yefomu
Amafomu ayinkimbinkimbi kakhulu angakhiwa kusetshenziswa amakilasi ethu egridi. Sebenzisa lokhu ngezakhiwo zefomu ezidinga amakholomu amaningi, ububanzi obuhlukahlukene, nezinketho ezengeziwe zokuqondanisa. Idinga $enable-grid-classes
okuguquguqukayo kwe-Sass ukuthi kuvulwe (kuvulwe ngokuzenzakalela).
<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>
Ama-Gutters
Ngokungeza amakilasi okulungisa i-gutter , ungaba nokulawula phezu kobubanzi be-gutter kanye ne-inline njengendlela yebhulokhi. Futhi idinga $enable-grid-classes
okuguquguqukayo kwe-Sass ukuthi kuvulwe (kuvulwe ngokuzenzakalela).
<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>
Izakhiwo eziyinkimbinkimbi kakhulu zingaphinda zidalwe ngesistimu yegridi.
<form class="row g-3">

</form>
Ifomu elivundlile
Dala amafomu avundlile ngegridi ngokwengeza .row
ikilasi ukuze wakhe amaqembu futhi usebenzise .col-*-*
amakilasi ukuze ucacise ububanzi bamalebula nezilawuli zakho. Qiniseka ukuthi ungeza .col-form-label
nezakho <label>
ukuze zimiswe ziqonde phakathi nezilawuli zazo zefomu ezihlotshaniswayo.
Ngezinye izikhathi, kungase kudingeke usebenzise imajini noma izinsiza zokunamathisela ukuze udale lokho kuqondanisa okuphelele okudingayo. Isibonelo, sisuse padding-top
ilebula yokokufaka kwerediyo estakiwe ukuze siqondanise kangcono isisekelo sombhalo.

Ukulinganisa kwelebula yefomu evundlile
Qiniseka ukuthi usebenzisa .col-form-label-sm
noma .col-form-label-lg
ku- <label>
s noma <legend>
u-s wakho ukulandela kahle usayizi .form-control-lg
we- .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>
Usayizi wekholomu
Njengoba kuboniswe ezibonelweni ezedlule, isistimu yethu yegridi ikuvumela ukuthi ubeke noma iyiphi inombolo ka- .col
s ngaphakathi kuka- .row
. Bazohlukanisa ububanzi obutholakalayo ngokulinganayo phakathi kwabo. Ungase futhi ukhethe isethi engaphansi yamakholomu akho ukuze uthathe isikhala esiningi noma esincane, kuyilapho u- .col
s esele ehlukanisa ngokulinganayo okunye, ngamakholomu athile amakilasi afana .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 class="col-sm">
<input type="text" class="form-control" placeholder="Zip" aria-label="Zip">
</div>
</div>
Ukulinganisa okuzenzakalelayo
Isibonelo esingezansi sisebenzisa insiza ye-flexbox ukubeka phakathi ngokuqondile okuqukethwe nezinguquko .col
ukuze .col-auto
amakholomu akho athathe kuphela isikhala esiningi njengoba kudingeka. Faka enye indlela, ubukhulu bekholomu ngokwawo ngokusekelwe kokuqukethwe.

Amafomu asemgqeni
Sebenzisa .row-cols-*
amakilasi ukuze udale izakhiwo ezivundlile eziphendulayo. Ngokungeza amakilasi okulungisa udoti , sizoba nama- gutter ezikhombisi-ndlela ezivundlile nezime mpo. Kumachweba wokubuka amaselula amancane, .col-12
isiza ukupakisha izilawuli zefomu nokunye okwengeziwe. I .align-items-center
-elementi iqondanisa izakhi zefomu phakathi nendawo, yenza .form-checkbox
ukuqondanisa kahle.
