It provides a code example to illustrate multiple selections:

In this example, the user can select more than one car brand. W3Schools further explains how to use the size attribute to control the number of visible options in a multi-select list.

Using the Optgroup Tag to Organize Options

W3Schools introduces the tag, which can be used to organize options into groups within the element. It explains how the label attribute can be used to give a name for the group.

Handling Select Tag Events
