Optional Attributes

The option element defines an option in the drop-down list. The <option> tag can be used without any attributes, but you usually need the value attribute, which indicates what is sent to the server. Use this tag in conjunction with the select element, elsewhere it is meaningless.
disabled Specifies that the option should be disabled when it first loads
label Defines a label to use when using <optgroup>
selected Specifies that the option should appear selected (will be displayed first in list) value=”selected”
value Defines the the value of the option to be sent to the server.
