Supported Form Controls
Bootstrap supports the following form controls:
- input
- textarea
- checkbox
- radio
- select
Bootstrap Input
Bootstrap supports all the HTML5 input types:
text, password, datetime, datetime-local, date, month, time, week, number,
email, url, search, tel, and color.
Note: Inputs will NOT be fully styled if their type is not properly declared!
The following example contains two input elements; one of type="text" and one of type="password". As we mentioned in the Forms chapter, we use the .form-control class to style inputs with full-width and proper padding, etc:
Example
<div class="form-group">
<label for="usr">Name:</label>
<input type="text" class="form-control" id="usr">
</div>
<div class="form-group">
<label for="pwd">Password:</label>
<input type="password" class="form-control" id="pwd">

Example
<div class="form-group">
<label for="comment">Comment:</label>
<textarea class="form-control" rows="5" id="comment"></textarea>

Bootstrap Checkboxes
Checkboxes are used if you want the user to select any number of options from
a list of preset options.
The following example contains three checkboxes. The last option is disabled:
Example
<div class="form-check">
<label class="form-check-label">
<input type="checkbox" class="form-check-input" value="">Option 1
</label>
</div>
<div class="form-check">
<label
class="form-check-label">
<input type="checkbox"
class="form-check-input" value="">Option 2
</label>
</div>
<div class="form-check disabled">
<label class="form-check-label">
<input type="checkbox" class="form-check-input" value="" disabled>Option 3
</label>
</div>Try it Yourself »
Example explained
Use a wrapper element with class="form-check" to ensure proper margins for labels and checkboxes.
Add the .form-check-label class to label elements, and .form-check-input to style checkboxes properly inside the .form-check container.
Inline Checkboxes
Use the .form-check-inline class if you want the checkboxes to appear on the
same line:
Example
<div class="form-check-inline">
<label class="form-check-label">
<input type="checkbox" class="form-check-input" value="">Option 1
</label>
</div>
<div class="form-check-inline">
<label
class="form-check-label">
<input type="checkbox"
class="form-check-input" value="">Option 2
</label>
</div>
<div class="form-check-inline disabled">
<label class="form-check-label">
<input type="checkbox" class="form-check-input" value="" disabled>Option 3
</label>
</div>Try it Yourself »
Bootstrap Radio Buttons
Radio buttons are used if you want to limit the user to just one selection
from a list of preset options.
The following example contains three radio buttons. The last option is disabled:
Example
<div class="form-check">
<label class="form-check-label">
<input type="radio" class="form-check-input"
name="optradio">Option 1
</label>
</div>
<div class="form-check">
<label
class="form-check-label">
<input type="radio"
class="form-check-input" name="optradio">Option 2
</label>
</div>
<div class="form-check disabled">
<label class="form-check-label">
<input type="radio" class="form-check-input" name="optradio" disabled>Option 3
</label>
</div>Try it Yourself »
As with checkboxes, use the .form-check-inline class if you want the
radio buttons to appear on the
same line:
Example
<div class="form-check-inline">
<label class="form-check-label">
<input type="radio" class="form-check-input" name="optradio">Option 1
</label>
</div>
<div class="form-check-inline">
<label
class="form-check-label">
<input type="radio"
class="form-check-input" name="optradio">Option 2
</label>
</div>
<div class="form-check-inline disabled">
<label class="form-check-label">
<input type="radio" class="form-check-input" name="optradio" disabled>Option 3
</label>
