You can add new options:

To start with options selected, put + before the option text (in first character)

• If the argument --multiple is missing, just the first option marked with + will start selected

Any of this ASCII signs \a \b \f \n \r \t in any part of options will be removed.

If --options"" is missing. Sample options will be loaded with 30 options.

You can customize message

Limitations

• Doesn't have a good compatibility with mac, I will work on this in future
• Uses bash array, so bash or similars are needed to run this script
• Terminal must have at least 8 lines for the script works. Maybe breaks in some cases with --message too. Resize terminal and press 'r'
• Don't have unit test
