HTML <datalist> Tag

The <datalist> tag in HTML is used to provide a pre-defined list of options for <input> elements. This allows users to input data by choosing from a list of options, rather than typing it out manually. The options in the datalist can be suggested as the user types in the input field, making it a useful feature for forms and search functions.

How to Use the <datalist> Tag

To use the <datalist> tag, you need to follow these steps:

1. Create an input field with the <input> tag.
2. Add a list attribute to the <input> tag and set it to the ID of the <datalist> element.
3. Create a <datalist> element with an ID that matches the list attribute in the <input> element.
4. Add <option> elements inside the <datalist> element to provide the list of options.

Main Attributes of the <datalist> Tag

Attribute	Description
id	Sets the ID of the <datalist> element, which is used to link it to an <input> element.

Example: Using the <datalist> Tag

Let's create an example where we have an input field for selecting a country from a list of options:

<input type="text" list="countries">
<datalist id="countries">
  <option value="USA">
  <option value="Canada">
  <option value="UK">
  <option value="Australia">
</datalist>

In this example, as the user types in the input field, a list of country options will be suggested based on the <datalist> element.
