Forms
Examples and usage guidelines for form control styles, layout options, and custom components for creating a wide variety of forms.
Default
Emphasized
Muted
Flushed
Masks
Heads up! In order to use the input masks you will need to include additional scripts in the page. See the Input Mask plugin .
Options
States
Sizing
Textarea
Default
<textarea class= "form-control" placeholder= "You can manually resize this textarea" rows= "3" ></textarea>
Non resizable
<textarea class= "form-control" placeholder= "This is a fixed height textarea" rows= "3" resize= "none" ></textarea>
Autosize
<textarea class= "form-control" data-toggle= "autosize" placeholder= "This textarea will autosize while you type" rows= "1" ></textarea>
Checkboxes
<div class= "custom-control custom-checkbox" >
<input type= "checkbox" class= "custom-control-input" id= "customCheck1" >
<label class= "custom-control-label" for= "customCheck1" > Check this custom checkbox</label>
</div>
Custom checkboxes can also utilize the :indeterminate
pseudo class when manually set via JavaScript (there is no available HTML attribute for specifying it).
<div class= "custom-control custom-checkbox" >
<input type= "checkbox" class= "custom-control-input" id= "customCheck2" data-toggle= "indeterminate" >
<label class= "custom-control-label" for= "customCheck2" > Check this custom checkbox</label>
</div>
The best part is that you can make checkboxes look like buttons, using any of the pre-defined colors and styles:
Radios
<div class= "custom-control custom-radio" >
<input type= "radio" id= "customRadio1" name= "customRadio" class= "custom-control-input" >
<label class= "custom-control-label" for= "customRadio1" > Toggle this custom radio</label>
</div>
<div class= "custom-control custom-radio" >
<input type= "radio" id= "customRadio2" name= "customRadio" class= "custom-control-input" >
<label class= "custom-control-label" for= "customRadio2" > Or toggle this other custom radio</label>
</div>
<div class= "custom-control custom-radio custom-control-inline" >
<input type= "radio" id= "customRadioInline1" name= "customRadioInline1" class= "custom-control-input" >
<label class= "custom-control-label" for= "customRadioInline1" > Toggle this custom radio</label>
</div>
<div class= "custom-control custom-radio custom-control-inline" >
<input type= "radio" id= "customRadioInline2" name= "customRadioInline1" class= "custom-control-input" >
<label class= "custom-control-label" for= "customRadioInline2" > Or toggle this other custom radio</label>
</div>
The same thing applies to radio buttons too. Make’em look like buttons, using any of the pre-defined colors and styles:
Switches
<div class= "custom-control custom-switch" >
<input type= "checkbox" class= "custom-control-input" id= "customSwitch1" >
<label class= "custom-control-label" for= "customSwitch1" > Toggle this switch element</label>
</div>
You may also choose from small and large custom selects to match our similarly sized text inputs.
Range
Create custom <input type="range">
controls with .custom-range
. The track (the background) and thumb (the value) are both styled to appear the same across browsers. As only IE and Firefox support “filling” their track from the left or right of the thumb as a means to visually indicate progress, we do not currently support it.
Range inputs have implicit values for min
and max—0
and 100
, respectively. You may specify new values for those using the min
and max
attributes.
By default, range inputs “snap” to integer values. To change this, you can specify a step
value. In the example below, we double the number of steps by using step="0.5"
.
File browser
<div>
<input type= "file" name= "file-1[]" id= "file-1" class= "custom-input-file" data-multiple-caption= "{count} files selected" multiple />
<label for= "file-1" >
<i class= "fa fa-upload" ></i>
<span> Choose a file…</span>
</label>
</div>
<div class= "mt-4" >
<input type= "file" name= "file-2[]" id= "file-2" class= "custom-input-file custom-input-file--2" data-multiple-caption= "{count} files selected" multiple />
<label for= "file-2" >
<i class= "fa fa-upload" ></i>
<span> Choose a file…</span>
</label>
</div>
Validation
Custom styles
For custom Bootstrap form validation messages, you’ll need to add the novalidate
boolean attribute to your <form>
. This disables the browser default feedback tooltips, but still provides access to the form validation APIs in JavaScript. Try to submit the form below; our JavaScript will intercept the submit button and relay feedback to you. When attempting to submit, you’ll see the :invalid
and :valid
styles applied to your form controls.
Custom feedback styles apply custom colors, borders, focus styles, and background icons to better communicate feedback. Background icons for <select>
s are only available with .custom-select
, and not .form-control
.
<form class= "needs-validation" novalidate >
<div class= "form-row" >
<div class= "col-md-4 mb-3" >
<label for= "validationCustom01" > First name</label>
<input type= "text" class= "form-control" id= "validationCustom01" placeholder= "First name" value= "Mark" required >
<div class= "valid-feedback" >
Looks good!
</div>
</div>
<div class= "col-md-4 mb-3" >
<label for= "validationCustom02" > Last name</label>
<input type= "text" class= "form-control" id= "validationCustom02" placeholder= "Last name" value= "Otto" required >
<div class= "valid-feedback" >
Looks good!

</div>
</div>
<div class= "form-group" >
<div class= "form-check" >
<input class= "form-check-input" type= "checkbox" value= "" id= "invalidCheck" required >
<label class= "form-check-label" for= "invalidCheck" >

</label>
<div class= "invalid-feedback" >

</div>
<button class= "btn btn-primary" type= "submit" > Submit form</button>
</form>
Browser defaults
Not interested in custom validation feedback messages or writing JavaScript to change form behaviors? All good, you can use the browser defaults. Try submitting the form below. Depending on your browser and OS, you’ll see a slightly different style of feedback.
While these feedback styles cannot be styled with CSS, you can still customize the feedback text through JavaScript.
<form>
<div class= "form-row" >
<div class= "col-md-4 mb-3" >
<label for= "validationDefault01" > First name</label>
<input type= "text" class= "form-control" id= "validationDefault01" placeholder= "First name" value= "Mark" required >
</div>
<div class= "col-md-4 mb-3" >
<label for= "validationDefault02" > Last name</label>
<input type= "text" class= "form-control" id= "validationDefault02" placeholder= "Last name" value= "Otto" required >
</div>
<div class= "col-md-4 mb-3" >
<label for= "validationDefaultUsername" > Username</label>
<div class= "input-group input-group-merge" >
<div class= "input-group-prepend" >
<span class= "input-group-text" id= "inputGroupPrepend2" > @</span>
</div>
<input type= "text" class= "form-control" id= "validationDefaultUsername" placeholder= "Username" aria-describedby= "inputGroupPrepend2" required >
</div>
</div>
</div>
<div class= "form-row" >
<div class= "col-md-6 mb-3" >
<label for= "validationDefault03" > City</label>
<input type= "text" class= "form-control" id= "validationDefault03" placeholder= "City" required >
</div>
<div class= "col-md-3 mb-3" >
<label for= "validationDefault04" > State</label>
<input type= "text" class= "form-control" id= "validationDefault04" placeholder= "State" required >
</div>
<div class= "col-md-3 mb-3" >
<label for= "validationDefault05" > Zip</label>
<input type= "text" class= "form-control" id= "validationDefault05" placeholder= "Zip" required >
</div>
</div>
<div class= "form-group" >
<div class= "form-check" >
<input class= "form-check-input" type= "checkbox" value= "" id= "invalidCheck2" required >
<label class= "form-check-label" for= "invalidCheck2" >
Agree to terms and conditions
</label>
</div>
</div>
<button class= "btn btn-primary" type= "submit" > Submit form</button>
</form>
Server side
We recommend using client-side validation, but in case you require server-side validation, you can indicate invalid and valid form fields with .is-invalid
and .is-valid
. Note that .invalid-feedback
is also supported with these classes.
<form>
<div class= "form-row" >
<div class= "col-md-4 mb-3" >
<label for= "validationServer01" > First name</label>
<input type= "text" class= "form-control is-valid" id= "validationServer01" placeholder= "First name" value= "Mark" required >
<div class= "valid-feedback" >
Looks good!
</div>
</div>

<label for= "validationServer02" > Last name</label>
