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:
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”>
</div>
Bootstrap Textarea
The following example contains a textarea:
Example
<div class=”form-group”>
<label for=”comment”>Comment:</label>
<textarea class=”form-control” rows=”5″ id=”comment”></textarea>
</div>
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=”checkbox”>
<label><input type=”checkbox” value=””>Option 1</label>
</div>
<div class=”checkbox”>
<label><input type=”checkbox” value=””>Option 2</label>
</div>
<div class=”checkbox disabled”>
<label><input type=”checkbox” value=”” disabled>Option 3</label>
</div>
Use the .checkbox-inline class if you want the checkboxes to appear on the same line:
Example
<label class=”checkbox-inline”><input type=”checkbox” value=””>Option 1</label>
<label class=”checkbox-inline”><input type=”checkbox” value=””>Option 2</label>
<label class=”checkbox-inline”><input type=”checkbox” value=””>Option 3</label>
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=”radio”>
<label><input type=”radio” name=”optradio”>Option 1</label>
</div>
<div class=”radio”>
<label><input type=”radio” name=”optradio”>Option 2</label>
</div>
<div class=”radio disabled”>
<label><input type=”radio” name=”optradio” disabled>Option 3</label>
</div>
Use the .radio-inline class if you want the radio buttons to appear on the same line:
Example
<label class=”radio-inline”><input type=”radio” name=”optradio”>Option 1</label>
<label class=”radio-inline”><input type=”radio” name=”optradio”>Option 2</label>
<label class=”radio-inline”><input type=”radio” name=”optradio”>Option 3</label>
Bootstrap Select List
Select lists are used if you want to allow the user to pick from multiple options.
The following example contains a dropdown list (select list):
Example
<div class=”form-group”>
<label for=”sel1″>Select list:</label>
<select class=”form-control” id=”sel1″>
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
</select>
</div>
