HTML <option> Tag

The <option> tag in HTML is used to define an option in a <select> element. The <select> element is used to create a drop-down list where users can select an option.

Each <option> tag represents an option in the drop-down list. It must be placed inside a <select> element.

Example:

<select>
  <option value="1">Option 1</option>
  <option value="2">Option 2</option>
  <option value="3">Option 3</option>
</select>  

In the above example, we have three options in the drop-down list: "Option 1", "Option 2", and "Option 3". Each <option> tag has a value attribute that specifies the value of the option.

Attributes of the <option> tag:

Attribute	Description
value	Specifies the value of the option. This is the value that will be sent to the server when the form is submitted.
selected	Specifies that the option should be pre-selected when the page loads.
disabled	Specifies that the option should be disabled and cannot be selected.
label	Specifies a label for the option. This can be used to display a custom label for the option.

Example with attributes:

<select>
  <option value="1" selected>Option 1</option>
  <option value="2" disabled>Option 2</option>
  <option value="3" label="Three">Option 3</option>
</select>  

In the above example, we have set different attributes for each option. The first option is pre-selected, the second option is disabled, and the third option has a custom label "Three".
