Synopsis

Read/Write

Whether the browser should render the SELECT element as a list box and allow users to make multiple selections from the list of options. By default the size property is set to the number of nested OPTION elements, but the value may be overridden with the size property setting. Users can select contiguous items by Shift-clicking on the first and last items of the group. To make discontiguous selections, Windows users must Ctrl-click on each item; Mac users must Command-click on each item. The multiple property has no effect when size is set to 1 to display a pop-up menu.

Example

if (document.entryForm.list3.multiple) {
    ...
}

Value

Boolean value: true | false.

Default
