HTML - list Attribute

The HTML list attribute refers to the datalist element that contains the predefined options for an input element. The value given to the list attribute should be the same as the id of the datalist element located in the same document.

The datalist element provides a list of predefined values to suggest to the user for this input.

Syntax

Following is the syntax of the HTML list attribute −

<tag list = "value" />

Where value should be the id value of the datalist element.

Example

In the following example, we are using the ‘list’ attribute with the input type=text.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML list attribute</title>
</head>
<body>
   <!--Example of the HTML list attribute -->
   <p>Click on input field and select from dropdown: </p>
   <input type="text" list="fruits">
   <datalist id='fruits'>
      <option value="Apple"></option>
      <option value="Banana"></option>
      <option value="Orange"></option>
      <option value="Grapes"></option>
      <option value="Pears"></option>
   </datalist>
</body>
</html>

When we run the above code, it will generate an output consisting of the input field that generates an dropdown menu when the user clicks on it.

Example

Considering the another scenario, where we are going to use the list attribute with the input type=number.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML list attribute</title>
</head>
<body>
   <!--Example of the HTML list attribute -->
   <p>Click on input field and select from dropdown: </p>
   <input type="number" list="numbers" placeholder="Select number..">
   <datalist id='numbers'>
      <option value="10"></option>
      <option value="20"></option>
      <option value="30"></option>
      <option value="40"></option>
      <option value="50"></option>
   </datalist>
</body>
</html>

On running the above code, the output window will pop up displaying the input field on the webpage. when the user clicks on the input field it will create a dropdown menu.

Example

Let's look into the following example, where we are going to use the list attribute with the input type=time.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML list attribute</title>
</head>
<body>
   <!--Example of the HTML list attribute -->
   <p>Click on input field and select from dropdown: </p>
   <input type="time" list="hours" placeholder="Select time..">
   <datalist id='hours'>
      <option value="12:00"></option>
      <option value="13:00"></option>
      <option value="14:00"></option>
      <option value="15:00"></option>
   </datalist>
</body>
</html>

When we run the above code, it will generate an output consisting of the input field displayed on the webpage. when the user clicks on the input field it will create a dropdown menu.
