A "option" element is an inline element that you can use to define one option of a dropdown input field in a form. Here are basic rules about a "option" element:
- "option" elements are inline elements.
- "option" elements can only be used as sub-elements of "select" elements.
- A "option" element can have empty content.
- A "option" element can have text content.
- A "option" element can have any sub-elements.
- A "option" element will be displayed by browsers as an option in a dropdown list.
There are two commonly used attributes for "option" elements:
- value="submitValue" - Specifies a specific value to be submitted if this option is selected. Without this attribute, the element content will be submitted.
- selected="selected" - Specifies that is option is selected by default.
Here is a tutorial example of "option" elements:
