Basic example
Individual form controls automatically receive some global styling. All textual <input>
, <textarea>
, and <select>
elements with .form-control
are set to width: 100%;
by default. Wrap labels and controls in .form-group
for optimum spacing.
<form role="form">
<div class="form-group">
<label for="exampleInputEmail1">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
</div>
<div class="form-group">
<label for="exampleInputPassword1">Password</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
</div>
<div class="form-group">
<label for="exampleInputFile">File input</label>
<input type="file" id="exampleInputFile">
<p class="help-block">Example block-level help text here.</p>
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Check me out
</label>
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
Don’t mix form groups with input groups
Do not mix form groups directly with input groups. Instead, nest the input group inside of the form group.
Inline form
Add .form-inline
to your <form>
for left-aligned and inline-block controls. This only applies to forms within viewports that are at least 768px wide.
Requires custom widths
Inputs, selects, and textareas are 100% wide by default in Bootstrap. To use the inline form, you’ll have to set a width on the form controls used within.
Always add labels
Screen readers will have trouble with your forms if you don’t include a label for every input. For these inline forms, you can hide the labels using the .sr-only
class.
<form class="form-inline" role="form">
<div class="form-group">
<label class="sr-only" for="exampleInputEmail2">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail2" placeholder="Enter email">
</div>
<div class="form-group">
<label class="sr-only" for="exampleInputPassword2">Password</label>
<input type="password" class="form-control" id="exampleInputPassword2" placeholder="Password">
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Remember me
</label>
</div>
<button type="submit" class="btn btn-default">Sign in</button>
</form>
Horizontal form
Use Bootstrap’s predefined grid classes to align labels and groups of form controls in a horizontal layout by adding .form-horizontal
to the form. Doing so changes .form-group
s to behave as grid rows, so no need for .row
.
<form class="form-horizontal" role="form">
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<input type="email" class="form-control" id="inputEmail3" placeholder="Email">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword3" placeholder="Password">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<div class="checkbox">
<label>
<input type="checkbox"> Remember me
</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Sign in</button>
</div>
</div>
</form>
Supported controls
Examples of standard form controls supported in an example form layout.
Inputs
Most common form control, text-based input fields. Includes support for all HTML5 types: text
, password
, datetime
, datetime-local
, date
, month
, time
, week
, number
, email
, url
, search
, tel
, and color
.
Type declaration required
Inputs will only be fully styled if their type
is properly declared.
<input type="text" class="form-control" placeholder="Text input">
Input groups
To add integrated text or buttons before and/or after any text-based <input>
, check out the input group component.
Textarea
Form control which supports multiple lines of text. Change rows
attribute as necessary.
<textarea class="form-control" rows="3"></textarea>
Checkboxes and radios
Checkboxes are for selecting one or several options in a list while radios are for selecting one option from many.
Default (stacked)
<div class="checkbox">
<label>
<input type="checkbox" value="">
Option one is this and that—be sure to include why it's great
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked>
Option one is this and that—be sure to include why it's great
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios2" value="option2">
Option two can be something else and selecting it will deselect option one
</label>
</div>
Inline checkboxes
Use the .checkbox-inline
or .radio-inline
classes on a series of checkboxes or radios for controls that appear on the same line.
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox2" value="option2"> 2
</label>
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox3" value="option3"> 3
</label>
Selects
Use the default option, or add multiple
to show multiple options at once.
<select class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
<select multiple class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
Static control
When you need to place plain text next to a form label within a horizontal form, use the .form-control-static
class on a <p>
.
<form class="form-horizontal" role="form">
<div class="form-group">
<label class="col-sm-2 control-label">Email</label>
<div class="col-sm-10">
<p class="form-control-static">email@example.com</p>
</div>
</div>
<div class="form-group">
<label for="inputPassword" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword" placeholder="Password">
</div>
</div>
</form>
Input focus
We remove the default outline
styles on some form controls and apply a box-shadow
in its place for :focus
.
Demo :focus
state
The above example input uses custom styles in our documentation to demonstrate the :focus
state on a .form-control
.
Disabled inputs
Add the disabled
attribute on an input to prevent user input and trigger a slightly different look.
<input class="form-control" id="disabledInput" type="text" placeholder="Disabled input here..." disabled>
Disabled fieldsets
Add the disabled
attribute to a <fieldset>
to disable all the controls within the <fieldset>
at once.
Link functionality of <a>
not impacted
This class will only change the appearance of <a class="btn btn-default">
buttons, not their functionality. Use custom JavaScript to disable links here.
Cross-browser compatibility
While Bootstrap will apply these styles in all browsers, Internet Explorer 9 and below don’t actually support the disabled
attribute on a <fieldset>
. Use custom JavaScript to disable the fieldset in these browsers.
<form role="form">
<fieldset disabled>
<div class="form-group">
<label for="disabledTextInput">Disabled input</label>
<input type="text" id="disabledTextInput" class="form-control" placeholder="Disabled input">
</div>
<div class="form-group">
<label for="disabledSelect">Disabled select menu</label>
<select id="disabledSelect" class="form-control">
<option>Disabled select</option>
</select>
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Can't check this
</label>
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</fieldset>
</form>
Validation states
Bootstrap includes validation styles for error, warning, and success states on form controls. To use, add .has-warning
, .has-error
, or .has-success
to the parent element. Any .control-label
, .form-control
, and .help-block
within that element will receive the validation styles.
<div class="form-group has-success">
<label class="control-label" for="inputSuccess1">Input with success</label>
<input type="text" class="form-control" id="inputSuccess1">
</div>
<div class="form-group has-warning">
<label class="control-label" for="inputWarning1">Input with warning</label>
<input type="text" class="form-control" id="inputWarning1">
</div>
<div class="form-group has-error">
<label class="control-label" for="inputError1">Input with error</label>
<input type="text" class="form-control" id="inputError1">
</div>
With optional icons
You can also add optional feedback icons with the addition of an extra class and the right icon.
Icons, labels, and input groups
Manual positioning of feedback icons is required for inputs without a label and for input groups with an add-on on the right. For inputs without labels, adjust the top
value. For input groups, adjust the right
value to an appropriate pixel value depending on the width of your addon.
<div class="form-group has-success has-feedback">
<label class="control-label" for="inputSuccess2">Input with success</label>
<input type="text" class="form-control" id="inputSuccess2">
<span class="glyphicon glyphicon-ok form-control-feedback"></span>
</div>
<div class="form-group has-warning has-feedback">
<label class="control-label" for="inputWarning2">Input with warning</label>
<input type="text" class="form-control" id="inputWarning2">
<span class="glyphicon glyphicon-warning-sign form-control-feedback"></span>
</div>
<div class="form-group has-error has-feedback">
<label class="control-label" for="inputError2">Input with error</label>
<input type="text" class="form-control" id="inputError2">
<span class="glyphicon glyphicon-remove form-control-feedback"></span>
</div>
Optional icons also work on horizontal and inline forms.
<form class="form-horizontal" role="form">
<div class="form-group has-success has-feedback">
<label class="control-label col-sm-3" for="inputSuccess3">Input with success</label>
<div class="col-sm-9">
<input type="text" class="form-control" id="inputSuccess3">
<span class="glyphicon glyphicon-ok form-control-feedback"></span>
</div>
</div>
</form>
<form class="form-inline" role="form">
<div class="form-group has-success has-feedback">
<label class="control-label" for="inputSuccess4">Input with success</label>
<input type="text" class="form-control" id="inputSuccess4">
<span class="glyphicon glyphicon-ok form-control-feedback"></span>
</div>
</form>
Control sizing
Set heights using classes like .input-lg
, and set widths using grid column classes like .col-lg-*
.
Height sizing
Create taller or shorter form controls that match button sizes.
<input class="form-control input-lg" type="text" placeholder=".input-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control input-sm" type="text" placeholder=".input-sm">
<select class="form-control input-lg">...</select>
<select class="form-control">...</select>
<select class="form-control input-sm">...</select>
Column sizing
Wrap inputs in grid columns, or any custom parent element, to easily enforce desired widths.
<div class="row">
<div class="col-xs-2">
<input type="text" class="form-control" placeholder=".col-xs-2">
</div>
<div class="col-xs-3">
<input type="text" class="form-control" placeholder=".col-xs-3">
</div>
<div class="col-xs-4">
<input type="text" class="form-control" placeholder=".col-xs-4">
</div>
</div>
Help text
Block level help text for form controls.
<span class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>
