Browser Compatibility

IEFirefoxOperaChromeSafari

All major browsers support the multiple attribute.

Definition and Usage

The multiple attribute is a boolean attribute.

The multiple attribute specifies that multiple options can be selected at once.

Selecting multiple options varies between different operating systems and browsers:

For Windows: Hold down the Control (ctrl) button to select multiple options
For Mac: Hold down the command button to select multiple options
The use of checkboxes is more user-friendly because the way this operation is performed is different, and because it is necessary to inform the user that multiple selections can be made.
