Javascript - How to make select option disable

To make a <select> option disabled in HTML, you can use the disabled attribute on the <option> element. Here's an example:

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Disabled Select Option</title> </head> <body> <label for="mySelect">Select an option:</label> <select id="mySelect"> <option value="option1">Option 1</option> <option value="option2">Option 2</option> <option value="option3" disabled>Option 3 (Disabled)</option> <option value="option4">Option 4</option> </select> </body> </html> 

In this example:

  • The third <option> has the disabled attribute, making it disabled.
  • Users won't be able to select or interact with the disabled option.

You can set the disabled attribute on any <option> element within the <select> to make it disabled. Adjust the values and content based on your specific use case.
