The <option> tag

Definition and Usage

The option element defines an option in the drop-down list. 

Differences Between HTML and XHTML

In HTML the <option> tag has no end tag.

In XHTML the <option> tag must be properly closed.

Tips and Notes

Note: The <option> tag can be used without any attributes, but you usually need the value attribute, which indicates what is sent to the server.

Note: Use this tag in conjunction with the select element, elsewhere it is meaningless. 

Example

Source Output
<select>
<option value ="volvo">Volvo</option>
