How do I set an un-selectable default description in a select (drop-down) menu in HTML?

Answer 1

Building on Oded's answer, you could also set the default option but not make it a selectable option if it's just dummy text. For example you could do:

Select a language

This would show "Select a language" before the user clicks the select box but the user wouldn't be able to select it because of the disabled attribute.
