HTML <datalist> Tag

What is HTML <datalist> Tag?

The HTML datalist tag is used to provide a list of predefined options for an input field. It helps users select a value from a dropdown list while still allowing them to type their own custom input. This tag is important because it improves user experience by combining the flexibility of a text box with the convenience of a dropdown. It is often used in forms where users must enter predictable data, such as country names, cities, or product types. The datalist tag works together with the input tag, where the input element uses the list attribute to link to the datalist.

Syntax of the HTML <datalist> Tag

  <option value="Option3">
</datalist>

The datalist element contains multiple option elements that define available choices. The input field linked to this datalist will display these options as suggestions when the user types.

Examples of HTML <datalist> Tag

Example 1: Basic HTML Datalist Tag

    <option value="Google Chrome">
    <option value="Mozilla Firefox">
    <option value="Safari">
    <option value="Microsoft Edge">
