Forms
Examples and usage guidelines for form control styles, layout options, and custom components for creating a wide variety of forms with the help of Bootstrap Forms.
Overview #
Bootstrap's form controls expand on Bootstrap Rebooted form styles with classes. Use these classes to opt into their customized displays for a more consistent rendering across browsers and devices.
Be sure to use an appropriate type
attribute on all inputs (e.g., email
for
email
address or number
for numerical
information) to take advantage of newer input
controls like email verification, number selection, and more.
For more information, see Bootstrap Forms
Here's a quick example to demonstrate Bootstrap's form styles. Keep reading for documentation on required classes, form layout, and more.
<form>
<div class="form-group">
<label for="exampleInputEmail1">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp" placeholder="Enter email">
<small id="emailHelp" class="form-text text-muted">We'll never share your email with anyone else.</small>
</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 form-check">
<input type="checkbox" class="form-check-input" id="exampleCheck1">
<label class="form-check-label" for="exampleCheck1">Check me out</label>
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
Form controls #
Textual form controls—like <input>
s,
<select>
s, and <textarea>
s—are styled with the
.form-control
class. Included are styles
for
general appearance, focus state, sizing, and more.
Be sure to explore our
custom form to further style <select>
s.
<form>
<div class="form-group">
<label for="exampleFormControlInput1">Email address</label>
<input type="email" class="form-control" id="exampleFormControlInput1" placeholder="name@example.com">
</div>
<div class="form-group">
<label for="exampleFormControlSelect1">Example select</label>
<select class="form-control" id="exampleFormControlSelect1">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
</div>
<div class="form-group">
<label for="exampleFormControlSelect2">Example multiple select</label>
<select multiple class="form-control" id="exampleFormControlSelect2">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
</div>
<div class="form-group">
<label for="exampleFormControlTextarea1">Example textarea</label>
<textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
</div>
</form>
For file inputs, swap the .form-control
for .form-control-file
.
<form>
<div class="form-group">
<label for="exampleFormControlFile1">Example file input</label>
<input type="file" class="form-control-file" id="exampleFormControlFile1">
</div>
</form>
Sizing #
Set heights using classes like .form-control-lg
and .form-control-sm
.
<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg">
<input class="form-control" type="text" placeholder="Default input">
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm">
<select class="form-control form-control-lg">
<option>Large select</option>
</select>
<select class="form-control">
<option>Default select</option>
</select>
<select class="form-control form-control-sm">
<option>Small select</option>
</select>
<select class="form-control form-control-xs">
<option>Extra small select</option>
</select>
Custom form #
Thedir customizes Bootstrap's forms, adds some styles to change default appearance
<div class="select-custom mb-4">
<select class="form-control">
<option>Option 1</option>
<option>Option 2</option>
</select>
</div>
<div class="arrows">
<select class="form-control form-control-lg">
<option>Option 1</option>
<option>Option 2</option>
</select>
</div>
Checkbox and radios #
Default checkboxes and radios are improved upon with the help of .form-check
,a
single class for both input types that improves the layout and behavior of their
HTML elements . Checkboxes are for selecting one or several options in
a list,
while radios are for selecting one option from many.
Disabled checkboxes and radios are supported, but to provide a not-allowed
cursor
on hover of the parent <label>
,
you’ll need to add the disabled
attribute
to the
.form-check-input
. The disabled attribute
will apply a lighter color to help
indicate the input’s state.
Checkboxes and radios use are built to support HTML-based form validation and
provide concise, accessible labels. As such, our <input>
s and <label>
s are
sibling elements as opposed to an <input>
within a <label>
. This is slightly
more verbose as you must specify id
and
for
attributes to relate the
<input>
and <label>
.
Default (stacked) #
By default, any number of checkboxes and radios that are immediate sibling will
be vertically stacked and appropriately spaced with .form-check
.
<div class="form-check">
<input class="form-check-input" type="checkbox" value="" id="defaultCheck1">
<label class="form-check-label" for="defaultCheck1">
Default checkbox
</label>
</div>
<div class="form-check">
<input class="form-check-input" type="checkbox" value="" id="defaultCheck2" disabled>
<label class="form-check-label" for="defaultCheck2">
Disabled checkbox
</label>
</div>
<div class="form-check">
<input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios1" value="option1" checked>
<label class="form-check-label" for="exampleRadios1">
Default radio
</label>
</div>
<div class="form-check">
<input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios2" value="option2">
<label class="form-check-label" for="exampleRadios2">

</label>
</div>
<div class="form-check">
<input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios3" value="option3" disabled>
<label class="form-check-label" for="exampleRadios3">

</label>
</div>
Inline checkbox #
Group checkboxes or radios on the same horizontal row by adding
.form-check-inline
to any .form-check
.

<label class="form-check-label" for="inlineCheckbox1">1</label>

within will automatically resize—no need for repeating the form control size
classes on each element.
Sizing on the individual input group elements isn’t supported.
