<h1>Forms</h1>

<h2>Controls and layouts</h2>
<p>Forms include styles for all the base form controls like <code>input</code>, <code>textarea</code>, and <code>select</code> you'd expect. There are also a number of custom components like appended and prepended inputs and support for lists of checkboxes.</p>
<p>Bootstrap provides simple markup and styles for four styles of common web forms. Each layout requires small changes to surrounding markup, but the controls themselves remain and behave the same.</p>
<p>Error, warning, and success states are included for form controls, as wel as disabled.</p>

<h3>Form validation</h3>
<p>It also includes validation styles for errors, warnings, and success. To use, add the error class to the surrounding <code>.control-group</code>.</p>

Option two can be something else and selecting it will deselect option one
&lt;/label&gt;
</pre>
<h4>Inline checkboxes</h4>
<p>Add the <code>.inline</code> class to a series of checkboxes or radios for controls appear on the same line.</p>
<form class="bs-docs-example">
<label class="checkbox inline">

<h2>Extending form controls</h2>
<h3>Prepend &amp; append inputs</h3>
<p>Input groups&mdash;with appended or prepended text&mdash;provide an easy way to give more context for your inputs. Great examples include the @ sign for Twitter usernames or $ for finances.</p>
<hr>
<h3>Checkboxes and radios</h3>
<p>Up to v1.4, Bootstrap required extra markup around checkboxes and radios to stack them. Now, it's a simple matter of repeating the <code>&lt;label class="checkbox"&gt;</code> that wraps the <code>&lt;input type="checkbox"&gt;</code>.</p>
<p>Inline checkboxes and radios are also supported. Just add <code>.inline</code> to any <code>.checkbox</code> or <code>.radio</code> and you're done.</p>
<hr>
<h4>Inline forms and append/prepend</h4>
<p>To use prepend or append inputs in an inline form, be sure to place the <code>.add-on</code> and <code>input</code> on the same line, without spaces.</p>
<hr>
<h4>Form help text</h4>
<p>To add help text for your form inputs, include inline help text with <code>&lt;span class="help-inline"&gt;</code> or a help text block with <code>&lt;p class="help-block"&gt;</code> after the input element.</p>
<p>Adding on top of existing browser controls, Bootstrap includes other useful form components.</p>

<h3>Prepended and appended inputs</h3>
<p>Add text or buttons before or after any text-based input.</p>
<h4>Default options</h4>
<p>Wrap a <code>.add-on</code> and an <code>input</code> with one of two classes to prepend or append text to an input.</p>
<form class="bs-docs-example form-inline">

&lt;/div&gt;
</pre>
<h4>Buttons instead of text</h4>
<p>Instead of a <code>&lt;span&gt;</code> with text, use a <code>.btn</code> to attach a button (or two) to an input.</p>

<h3>Control sizing</h3>
<p>Use relative sizing classes like <code>.input-large</code> or match your inputs to the grid column sizes using <code>.span*</code> classes.</p>
<h4>Relative sizing</h4>
<form class="bs-docs-example">
<div class="controls docs-input-sizes">
<input class="input-mini" type="text" placeholder=".input-mini">
<input class="input-small" type="text" placeholder=".input-small">
<input class="input-medium" type="text" placeholder=".input-medium">
<input class="input-large" type="text" placeholder=".input-large">
<input class="input-xlarge" type="text" placeholder=".input-xlarge">
<input class="input-xxlarge" type="text" placeholder=".input-xxlarge">
</div>
</form>
<pre class="prettyprint linenums">
&lt;input class="input-mini" type="text"&gt;
&lt;input class="input-small" type="text"&gt;
&lt;input class="input-medium" type="text"&gt;
&lt;input class="input-large" type="text"&gt;
&lt;input class="input-xlarge" type="text"&gt;
&lt;input class="input-xxlarge" type="text"&gt;
</pre>
<h4>Grid sizing</h4>
<p>Use <code>.span1</code> to <code>.span12</code> for inputs that match the same sizes of the grid columns.</p>
<form class="bs-docs-example">
<div class="controls docs-input-sizes">
<input class="span1" type="text" placeholder=".span1">
<input class="span2" type="text" placeholder=".span2">
<input class="span3" type="text" placeholder=".span3">
<select class="span1">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
<select class="span2">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
<select class="span3">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
</div>
</form>
<pre class="prettyprint linenums">
&lt;input class="span1" type="text"&gt;
&lt;input class="span2" type="text"&gt;
&lt;input class="span3" type="text"&gt;
</pre>
<h3>Uneditable inputs</h3>
<p>Present data in a form that's not editable without using actual form markup.</p>
<form class="bs-docs-example">
<span class="input-xlarge uneditable-input">Some value here</span>
</form>
<pre class="prettyprint linenums">
&lt;span class="input-xlarge uneditable-input"&gt;Some value here&lt;/span&gt;
</pre>
<h3>Form actions</h3>
<p>End a form with a group of actions (buttons). When placed within a <code>.form-horizontal</code>, the buttons will automatically indent to line up with the form controls.</p>
<form class="bs-docs-example">
<div class="form-actions">
<button type="submit" class="btn btn-primary">Save changes</button>
<button class="btn">Cancel</button>
</div>
</form>
<pre class="prettyprint linenums">
&lt;div class="form-actions"&gt;
&lt;button type="submit" class="btn btn-primary"&gt;Save changes&lt;/button&gt;
&lt;button class="btn"&gt;Cancel&lt;/button&gt;
&lt;/div&gt;
</pre>
<h3>Help text</h3>
<p>Inline and block level support for help text that appears around form controls.</p>
<h4>Inline help</h4>
<form class="bs-docs-example form-inline">
<input type="text"> <span class="help-inline">Inline help text</span>
</form>
<pre class="prettyprint linenums">
&lt;span class="help-inline"&gt;Inline help text&lt;/span&gt;
</pre>
<h4>Block help</h4>
<form class="bs-docs-example form-inline">
<input type="text">
<span class="help-block">A longer block of help text that breaks onto a new line and may extend beyond one line.</span>
</form>
<pre class="prettyprint linenums">
&lt;span class="help-block"&gt;A longer block of help text that breaks onto a new line and may extend beyond one line.&lt;/span&gt;
</pre>
<hr class="bs-docs-separator"></hr>
<h2>Form control states</h2>
<p>Provide feedback to users or visitors with basic feedback states on form controls and labels.</p>
<h3>Input focus</h3>
<p>We remove the default <code>outline</code> styles on some form controls and apply a <code>box-shadow</code> in its place for <code>:focus</code>.</p>
<form class="bs-docs-example form-inline">
<input class="input-xlarge focused" id="focusedInput" type="text" value="This is focused...">
</form>
<pre class="prettyprint linenums">
&lt;input class="input-xlarge" id="focusedInput" type="text" value="This is focused..."&gt;
</pre>
<h3>Disabled inputs</h3>
<p>Add the <code>disabled</code> attribute on an input to prevent user input and trigger a slightly different look.</p>
<form class="bs-docs-example form-inline">
<input class="input-xlarge" id="disabledInput" type="text" placeholder="Disabled input here…" disabled>
</form>
<pre class="prettyprint linenums">
&lt;input class="input-xlarge" id="disabledInput" type="text" placeholder="Disabled input here..." disabled&gt;
</pre>
<h3>Validation states</h3>
<p>Bootstrap includes validation styles for error, warning, and success messages. To use, add the appropriate class to the surrounding <code>.control-group</code>.</p>
<form class="bs-docs-example form-horizontal">
<div class="control-group warning">
<label class="control-label" for="inputWarning">Input with warning</label>
<div class="controls">
<input type="text" id="inputWarning">
<span class="help-inline">Something may have gone wrong</span>
</div>
</div>
<div class="control-group error">
<label class="control-label" for="inputError">Input with error</label>
<div class="controls">
<input type="text" id="inputError">
<span class="help-inline">Please correct the error</span>
</div>
</div>
<div class="control-group success">
<label class="control-label" for="inputSuccess">Input with success</label>
<div class="controls">
<input type="text" id="inputSuccess">
<span class="help-inline">Woohoo!</span>
</div>
</div>
</form>
<pre class="prettyprint linenums">
&lt;div class="control-group warning"&gt;
&lt;label class="control-label" for="inputWarning"&gt;Input with warning&lt;/label&gt;
&lt;div class="controls"&gt;
&lt;input type="text" id="inputWarning"&gt;
&lt;span class="help-inline"&gt;Something may have gone wrong&lt;/span&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;div class="control-group error"&gt;
&lt;label class="control-label" for="inputError"&gt;Input with error&lt;/label&gt;
&lt;div class="controls"&gt;
&lt;input type="text" id="inputError"&gt;
&lt;span class="help-inline"&gt;Please correct the error&lt;/span&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;div class="control-group success"&gt;
&lt;label class="control-label" for="inputSuccess"&gt;Input with success&lt;/label&gt;
&lt;div class="controls"&gt;
&lt;input type="text" id="inputSuccess"&gt;
&lt;span class="help-inline"&gt;Woohoo!&lt;/span&gt;
&lt;/div&gt;
&lt;/div&gt;
