<datalist>: The HTML Data List element
======================================

The **`<datalist>`** HTML element contains a set of `<option>` elements that represent the permissible or recommended options available to choose from within other controls.

Try it
------

 To bind the `<datalist>` element to the control, we give it a unique identifier in the `id` attribute, and then add the `list` attribute to the `<input>` element with the same identifier as value.
 Only certain types of `<input>` support this behavior, and it can also vary from browser to browser.

**Note:** The `<option>` element can store a value as internal content and in the `value` and `label` attributes. Which one will be visible in the drop-down menu depends on the browser, but when clicked, content entered into control field will always come from the `value` attribute.

Attributes
----------

This element has no other attributes than the global attributes, common to all elements.

Examples
--------

### Textual types

 Recommended values in types text, search, url, tel, email and number, are displayed in a drop-down menu when user clicks or double-clicks on the control.
 Typically the right side of a control will also have an arrow pointing to the presence of predefined values.


```html
<label for="myBrowser">Choose a browser from this list:</label>
<input list="browsers" id="myBrowser" name="myBrowser" />
<datalist id="browsers">
  <option value="Chrome"></option>
  <option value="Firefox"></option>
  <option value="Opera"></option>
  <option value="Safari"></option>
  <option value="Microsoft Edge"></option>
</datalist>
```

### Date and Time types

 The types month, week, date, time and datetime-local can show an interface that allows a convenient selection of a date and time.
 Predefined values can be shown there, allowing the user to quickly fill the control value.

**Note:** When type is not supported, `text` type creating simple text field will be used instead. That field will correctly recognize recommended values and display them to the user in a drop-down menu.


```html
<input type="time" list="popularHours" />
<datalist id="popularHours">
  <option value="12:00"></option>
  <option value="13:00"></option>
  <option value="14:00"></option>
</datalist>
```

### Range type

The recommended values in the range type will be shown as series of hash marks that the user can easily select.


```html
<label for="tick">Tip amount:</label>
<input type="range" list="tickmarks" min="0" max="100" id="tick" name="tick" />
<datalist id="tickmarks">
  <option value="0"></option>
  <option value="10"></option>
  <option value="20"></option>
  <option value="30"></option>
</datalist>
```

### Color type

The color type can show predefined colors in a browser-provided interface.


```html
<label for="colors">Pick a color (preferably a red tone):</label>
<input type="color" list="redColors" id="colors" />
<datalist id="redColors">
  <option value="#800000"></option>
  <option value="#8B0000"></option>
  <option value="#A52A2A"></option>
  <option value="#DC143C"></option>
</datalist>
```

### Password type

The specification allows linking `<datalist>` with a password type, but no browser supports it for security reasons.


```html
<label for="pwd">Enter a password:</label>
<input type="password" list="randomPassword" id="pwd" />
<datalist id="randomPassword">
  <option value="5Mg[\_3DnkgSu@!q#"></option>
</datalist>
```

Accessibility concerns
----------------------

When deciding to use the `<datalist>` element, here are some accessibility issues to be mindful of:

* The font size of the data list's options does not zoom, always remaining the same size. The contents of the autosuggest do not grow or shrink when the rest of the contents are zoomed in or out.
* As targeting the list of options with CSS is very limited to non-existent, rendering can not be styled for high-contrast mode.
* Some screen reader/browser combinations, including NVDA and Firefox, do not announce the contents of the autosuggest popup.
