How does the "required" attribute affect the validation of a dropdown list in a form?

  • It forces the user to select a radio button. 
  • It ensures a checkbox is ticked. 
  • It ensures an option other than the default is chosen. 
  • It auto-selects the first option. 
The required attribute, when added to a form control, ensures that the user provides a value or makes a selection before submitting the form. For a dropdown list, it means the user must select an option other than the default (especially if the default is a prompt like "Please choose an option") to successfully submit the form.
