Opmaak
Jou jo formulieren wat struktuer - fan ynline oant horizontale oant oanpaste rasterimplementaasjes - mei ús opsjes foar formulierlayout.
Formulieren
Elke groep formulierfjilden moat yn in <form>
elemint wenje. Bootstrap jout gjin standert styling foar it <form>
elemint, mar d'r binne wat krêftige browserfunksjes dy't standert wurde levere.
- Nij by browserformulieren? Tink derom om de MDN-formulierdokuminten te besjen foar in oersjoch en folsleine list mei beskikbere attributen.
<button>
s binnen in<form>
standert oantype="submit"
, stribje dus nei spesifyk te wêzen en befetsje altyd intype
.- Jo kinne elk formulierelemint yn in formulier útskeakelje mei it
disabled
attribút op 'e<form>
.
Sûnt Bootstrap jildt display: block
en width: 100%
foar hast al ús formulierkontrôles, sille formulieren standert fertikaal steapele wurde. Oanfoljende klassen kinne brûkt wurde om dizze yndieling per formulier te feroarjen.
Utilities
Marge-nutsbedriuwen binne de maklikste manier om wat struktuer ta te foegjen oan formulieren. Se leverje basisgroepearring fan labels, kontrôles, opsjonele formuliertekst, en formuliervalidaasjeberjochten. Wy riede oan te hâlden oan margin-bottom
nutsbedriuwen, en in inkele rjochting yn 'e hiele foarm te brûken foar konsistinsje.
Fiel jo frij om jo formulieren te bouwen lykas jo wolle, mei <fieldset>
s, <div>
s, of hast elk oar elemint.
<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>
Raster foarmje
Mear komplekse foarmen kinne wurde boud mei ús rasterklassen. Brûk dizze foar formulierlayouts dy't meardere kolommen, farieare breedtes en ekstra ôfstimmingsopsjes nedich binne. Fereasket dat de $enable-grid-classes
Sass-fariabele ynskeakele is (standert oan).
<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>
Gutters
Troch it tafoegjen fan gootmodifierklassen kinne jo kontrôle hawwe oer de gootbreedte yn sawol de ynline as blokrjochting. Fereasket ek dat de $enable-grid-classes
Sass-fariabele ynskeakele is (standert oan).
<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>
Mear komplekse yndielingen kinne ek makke wurde mei it rastersysteem.
<form class="row g-3">
<div class="col-md-6">
<label for="inputEmail4" class="form-label">Email</label>
<input type="email" class="form-control" id="inputEmail4">

<div class="col-12">
<button type="submit" class="btn btn-primary">Sign in</button>
</div>
</form>
Horizontale foarm
Meitsje horizontale formulieren mei it raster troch de .row
klasse ta te foegjen om groepen te foarmjen en de .col-*-*
klassen te brûken om de breedte fan jo labels en kontrôles op te jaan. Wês wis dat jo ek tafoegje .col-form-label
oan jo <label>
s, sadat se fertikaal sintraal binne mei har assosjearre formulierkontrôles.
Soms moatte jo miskien marzje- of padding-hulpprogramma's brûke om dy perfekte ôfstimming te meitsjen dy't jo nedich binne. Wy hawwe bygelyks it padding-top
label op ús opsteapele radio-ynputen fuortsmiten om de tekstbasisline better op te rjochtsjen.
<form>
<div class="row mb-3">
<label for="inputEmail3" class="col-sm-2 col-form-label">Email</label>

Horizontale foarm label sizing
Wês wis dat jo .col-form-label-sm
of .col-form-label-lg
nei jo <label>
s of <legend>
s brûke om de grutte fan .form-control-lg
en korrekt te folgjen .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 class="col-sm-10">
<input type="email" class="form-control form-control-sm" id="colFormLabelSm" placeholder="col-form-label-sm">

<div class="row mb-3">
<label for="colFormLabel" class="col-sm-2 col-form-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="colFormLabel" placeholder="col-form-label">

<div class="row">
<label for="colFormLabelLg" class="col-sm-2 col-form-label col-form-label-lg">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control form-control-lg" id="colFormLabelLg" placeholder="col-form-label-lg">
</div>
</div>
Kolom grutte
Lykas yn 'e foargeande foarbylden sjen litten, lit ús rastersysteem jo elk oantal .col
s binnen in pleatse .row
. Se sille de beskikbere breedte gelyk tusken har splitse. Jo kinne ek in subset fan jo kolommen kieze om mear of minder romte yn te nimmen, wylst de oerbleaune .col
s de rest lykweardich splitst, mei spesifike kolomklassen lykas .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>
Auto-sizing
It foarbyld hjirûnder brûkt in flexbox-helpmiddel om de ynhâld fertikaal te centreren en te feroarjen .col
sadat .col-auto
jo kolommen allinich safolle romte ynnimme as nedich. Mei oare wurden, de kolom grutte sels basearre op de ynhâld.
<form class="row gy-2 gx-3 align-items-center">
<div class="col-auto">
<label class="visually-hidden" for="autoSizingInput">Name</label>
<input type="text" class="form-control" id="autoSizingInput" placeholder="Jane Doe">
</div>
<div class="col-auto">
<label class="visually-hidden" for="autoSizingInputGroup">Username</label>
<div class="input-group">
<div class="input-group-text">@</div>
<input type="text" class="form-control" id="autoSizingInputGroup" placeholder="Username">
</div>
</div>
<div class="col-auto">
<label class="visually-hidden" for="autoSizingSelect">Preference</label>
<select class="form-select" id="autoSizingSelect">
<option selected>Choose...</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
</div>
<div class="col-auto">
<div class="form-check">
<input class="form-check-input" type="checkbox" id="autoSizingCheck">
<label class="form-check-label" for="autoSizingCheck">
Remember me
</label>
</div>
</div>
<div class="col-auto">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
Jo kinne dat dan nochris remixe mei grutte-spesifike kolomklassen.
<form class="row gx-3 gy-2 align-items-center">
<div class="col-sm-3">
<label class="visually-hidden" for="specificSizeInputName">Name</label>

</div>
<div class="col-auto">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</form>
Inline formulieren
Brûk de .row-cols-*
klassen om responsive horizontale layouts te meitsjen. Troch it tafoegjen fan klassen foar modifikaasje fan gutter , sille wy goten hawwe yn horizontale en fertikale rjochtingen. Op smelle mobile viewports .col-12
helpt de formulierkontrôles en mear te stapeljen. It .align-items-center
rjochtet de foarmeleminten nei it midden, wêrtroch't de .form-checkbox
rjochting goed is.
<form class="row row-cols-lg-auto g-3 align-items-center">
<div class="col-12">
<label class="visually-hidden" for="inlineFormInputGroupUsername">Username</label>
<div class="input-group">
