The value attribute specifies the value of an <input> element.

The value attribute is used differently for different input types:

  • For “button”, “reset”, and “submit” - it defines the text on the button
  • For “text”, “password”, and “hidden” - it defines the initial (default) value of the input field
  • For “checkbox”, “radio”, “image” - it defines the value associated with the input (this is also the value that is sent on submit)

Note: The value attribute cannot be used with <input type="file"> .

To what I think is your question, what is the use of the “value” in this:

<option disabled selected value>Select an option</option>

I don’t know. But I do notice the the validation that confirms “required” for this select doesn’t seem to work without it.

but in this instance it is a “boolean” attribute, (does not have =“something” at the end of “value” like value=“jack”
what do you think about that?

Being blank doesn’t make it a boolean attribute. You can get better clarification in MDN docs.
