Forms are the standard way to receive user inputted data. The transitions and smoothness of these elements are very important because of the inherent user interaction associated with forms.

## Input fields

Text fields allow user input. The border should light up simply and clearly indicating which field the user is currently editing. You must have a `.input-field` div wrapping your input and label. This helps our jQuery animate the label. This is only used in our Input and Textarea form elements.

If you don't want the Green and Red validation states, just remove the `validate` class from your inputs.

First Name
Last Name
Disabled
Password
Email

      <div class="row">
        <form class="col s12">
          <div class="row">
            <div class="input-field col s6">
              <input placeholder="Placeholder" id="first_name" type="text" class="validate">
              <label for="first_name">First Name</label>
            </div>
            <div class="input-field col s6">
              <input id="last_name" type="text" class="validate">
              <label for="last_name">Last Name</label>
            </div>
          </div>
          <div class="row">
            <div class="input-field col s12">
              <input disabled value="I am not editable" id="disabled" type="text" class="validate">
              <label for="disabled">Disabled</label>
            </div>
          </div>
          <div class="row">
            <div class="input-field col s12">
              <input id="password" type="password" class="validate">
              <label for="password">Password</label>
            </div>
          </div>
          <div class="row">
            <div class="input-field col s12">
              <input id="email" type="email" class="validate">
              <label for="email">Email</label>
            </div>
          </div>
        </form>
      </div>

#### Prefilling Text Inputs

If you are having trouble with the labels overlapping prefilled content, Try adding `class="active"` to the label

First Name

      <div class="row">
        <div class="input-field col s6">
          <input value="Alvin" id="first_name2" type="text" class="validate">
          <label class="active" for="first_name2">First Name</label>
        </div>
      </div>

#### Icon Prefixes

You can add an icon prefix to make the form input label even more clear. Just add an icon with the class `prefix` before the input and label.

account_circle First Name
phone Telephone

      <div class="row">
        <form class="col s12">
          <div class="row">
            <div class="input-field col s6">
              <i class="material-icons prefix">account_circle</i>
              <input id="icon_prefix" type="text" class="validate">
              <label for="icon_prefix">First Name</label>
            </div>
            <div class="input-field col s6">
              <i class="material-icons prefix">phone</i>
              <input id="icon_telephone" type="tel" class="validate">
              <label for="icon_telephone">Telephone</label>
            </div>
          </div>
        </form>
      </div>

#### Custom Error or Success Messages

You can add custom validation messages by adding either `data-error` or `data-success` attributes to your input field labels.

Email

      <div class="row">
        <form class="col s12">
          <div class="row">
            <div class="input-field col s12">
              <input id="email" type="email" class="validate">
              <label for="email" data-error="wrong" data-success="right">Email</label>
            </div>
          </div>
        </form>
      </div>

#### Changing colors

Here is a CSS template for modifying input fields in CSS. With Sass, you can achieve this by just changing a variable. The CSS shown below is unprefixed. Depending on what you use, you may have to change the type attribute selector.

      /* label color */
       .input-field label {
         color: #000;
       }
       /* label focus color */
       .input-field input[type=text]:focus + label {
         color: #000;
       }
       /* label underline focus color */
       .input-field input[type=text]:focus {
         border-bottom: 1px solid #000;
         box-shadow: 0 1px 0 0 #000;
       }
       /* valid color */
       .input-field input[type=text].valid {
         border-bottom: 1px solid #000;
         box-shadow: 0 1px 0 0 #000;
       }
       /* invalid color */
       .input-field input[type=text].invalid {
         border-bottom: 1px solid #000;
         box-shadow: 0 1px 0 0 #000;
       }
       /* icon prefix focus color */
       .input-field .prefix.active {
         color: #000;
       }

## Textarea

Textareas allow larger expandable user input. The border should light up simply and clearly indicating which field the user is currently editing. You must have a `.input-field` div wrapping your input and label. This helps our jQuery animate the label. This is only used in our Input and Textarea form elements.

Textareas will auto resize to the text inside.

Textarea

      <div class="row">
        <form class="col s12">
          <div class="row">
            <div class="input-field col s12">
              <textarea id="textarea1" class="materialize-textarea"></textarea>
              <label for="textarea1">Textarea</label>
            </div>
          </div>
        </form>
      </div>

advanced note: When dynamically changing the value of a textarea with methods like jQuery's `.val()`, you must trigger an autoresize on it afterwords because .val() does not automatically trigger the events we've binded to the textarea.

      $('#textarea1').val('New Text');
      $('#textarea1').trigger('autoresize');

#### Icon Prefixes

You can add an icon prefix to make the form input label even more clear. Just add an icon with the class `prefix` before the input and label.

mode_edit Message

      <div class="row">
        <form class="col s12">
          <div class="row">
            <div class="input-field col s6">
              <i class="material-icons prefix">mode_edit</i>
              <textarea id="icon_prefix2" class="materialize-textarea"></textarea>
              <label for="icon_prefix2">First Name</label>
            </div>
          </div>
        </form>
      </div>

## Select

Select allows user input through specified options. Make sure you wrap it in a `.input-field` for proper alignment with other text fields.

Materialize Select

You can add the property `multiple` to get the multiple select and select several options.

Materialize Multiple Select

We also support optgroups in our selects.

Optgroups

You can add icons to your options in any type of select. In the option you add the image source with the `data-icon` attribute. You can add the `left` or `right` class to align your icon. You can also add the `circle` class to your icon.

Images in select

You can add the class `browser-default` to get the browser default.

Browser Select

      <div class="input-field col s12">
        <select>
          <option value="" disabled selected>Choose your option</option>
          <option value="1">Option 1</option>
          <option value="2">Option 2</option>
          <option value="3">Option 3</option>
        </select>
        <label>Materialize Select</label>
      </div>

      <div class="input-field col s12">
        <select multiple>
          <option value="" disabled selected>Choose your option</option>
          <option value="1">Option 1</option>
          <option value="2">Option 2</option>
          <option value="3">Option 3</option>

          </optgroup>
          <optgroup label="team 2">
            <option value="3">Option 3</option>
            <option value="4">Option 4</option>

        </select>
        <label>Optgroups</label>

        </select>
        <label>Images in select</label>
      </div>

      <label>Browser Select</label>
      <select class="browser-default">

        <option value="2">Option 2</option>
        <option value="3">Option 3</option>
      </select>

#### Disabled Styles

You can also add `disabled` to the select element to make the whole thing disabled. Or if you add `disabled` to the options, the individual options will be unselectable.

Materialize Disabled
Browser Disabled

      <label>Materialize Disabled</label>
      <select disabled>
        <option value="" disabled selected>Choose your option</option>
        <option value="1">Option 1</option>
        <option value="2">Option 2</option>
        <option value="3">Option 3</option>
      </select>

      <label>Browser Disabled</label>
      <select class="browser-default" disabled>
        <option value="" disabled selected>Choose your option</option>
        <option value="1">Option 1</option>
        <option value="2">Option 2</option>
        <option value="3">Option 3</option>
      </select>

#### Initialization

You must initialize the select element as shown below. In addition, you will need a separate call for any dynamically generated select elements your page generates.

      $(document).ready(function() {
        $('select').material_select();
      });

#### Updating/Destroying Select

If you want to update the items inside the select, just rerun the initialization code from above after editing the original select. Or you can destroy the material select with this function below, and create a new select altogether

      $('select').material_select('destroy');

## Radio Buttons

Radio Buttons are used when the user must make only one selection out of a group of items

Red

Yellow

Green

Brown

Add radio buttons to a group by adding the name attribute along with the same corresponding value for each of the radio buttons in the group. Create disabled radio buttons by adding the disabled attribute as shown below.

      <form action="#">
        <p>
          <input name="group1" type="radio" id="test1" />
          <label for="test1">Red</label>
        </p>
        <p>
          <input name="group1" type="radio" id="test2" />
          <label for="test2">Yellow</label>
        </p>
        <p>
          <input class="with-gap" name="group1" type="radio" id="test3"  />
          <label for="test3">Green</label>
        </p>
          <p>
            <input name="group1" type="radio" id="test4" disabled="disabled" />
            <label for="test4">Brown</label>
        </p>
      </form>

#### Options

To create a radio button with a gap, add `class="with-gap"` to your input. See the example below.

Red

      <p>
        <input class="with-gap" name="group3" type="radio" id="test5" checked />
        <label for="test5">Red</label>
      </p>

## Checkboxes

Use checkboxes when looking for yes or no answers. The `for` attribute is necessary to bind the our custom checkbox with the input. Add the input's `id` as the value of the `for` attribute of the label.

Red

Yellow

Filled in

Indeterminate Style

Green

Brown

      <form action="#">
        <p>
          <input type="checkbox" id="test5" />
          <label for="test5">Red</label>
        </p>
        <p>
          <input type="checkbox" id="test6" checked="checked" />
          <label for="test6">Yellow</label>
        </p>
        <p>
          <input type="checkbox" class="filled-in" id="filled-in-box" checked="checked" />
          <label for="filled-in-box">Filled in</label>
        </p>
        <p>
          <input type="checkbox" id="test7" checked="checked" disabled="disabled" />
          <label for="test7">Green</label>
        </p>
          <p>
            <input type="checkbox" id="test8" disabled="disabled" />
            <label for="test8">Brown</label>
        </p>
      </form>

## Switches

Off On

Off On

      <!-- Switch -->
      <div class="switch">
        <label>
          Off
          <input type="checkbox">
          <span class="lever"></span>
          On
        </label>
      </div>

      <!-- Disabled Switch -->
      <div class="switch">
        <label>
          Off
          <input disabled type="checkbox">
          <span class="lever"></span>
          On
        </label>
      </div>

## File Input

If you want to style an input button with a path input we provide this structure.

File

      <form action="#">
        <div class="file-field input-field">
          <div class="btn">
            <span>File</span>
            <input type="file">
          </div>
          <div class="file-path-wrapper">
            <input class="file-path validate" type="text">
          </div>
        </div>
      </form>

You can also use the `multiple` attribute to allow multiple file uploads.

File

      <form action="#">
        <div class="file-field input-field">
          <div class="btn">
            <span>File</span>
            <input type="file" multiple>
          </div>
          <div class="file-path-wrapper">
            <input class="file-path validate" type="text" placeholder="Upload one or more files">
          </div>
        </div>
      </form>

## Range

Add a range slider for values with a wide range. This one is set to be a number between 0 and 100. We have two different types of sliders. nouiSlider is a 3rd party plugin which we've modified. To use the noUiSlider, you will have to manually link the `nouislider.css` and `nouislider.js` files located in the extras folder.

#### noUiSlider

See noUiSlider's official documentation here to see a variety of slider options

      var slider = document.getElementById('test5');
      noUiSlider.create(slider, {
       start: [20, 80],
       connect: true,
       step: 1,
       range: {
         'min': 0,
         'max': 100
       },
       format: wNumb({
         decimals: 0
       })
      });

#### HTML5 Range

      <form action="#">
        <p class="range-field">
          <input type="range" id="test5" min="0" max="100" />
        </p>
      </form>

## Date Picker

We use a modified version of pickadate.js to create a materialized date picker. Test it out below!

Birthdate

      <input type="date" class="datepicker">

#### Initialization

At this time, not all pickadate.js options are working with our implementation

      $('.datepicker').pickadate({
        selectMonths: true, // Creates a dropdown to control month
        selectYears: 15 // Creates a dropdown of 15 years to control year
      });

## Character Counter

Use a character counter in fields where a character restriction is in place.

Input text
Textarea

        <div class="row">
          <form class="col s12">
            <div class="row">
              <div class="input-field col s6">
                <input id="input_text" type="text" length="10">
                <label for="input_text">Input text</label>
              </div>
            </div>
            <div class="row">
              <div class="input-field col s12">
                <textarea id="textarea1" class="materialize-textarea" length="120"></textarea>
                <label for="textarea1">Textarea</label>
              </div>
            </div>
          </form>
        </div>

#### Initialization

There are no options for this plugin, but if you are adding these dynamically, you can use this to initialize them.

      $(document).ready(function() {
        $('input#input_text, textarea#textarea1').characterCounter();
      });
