---

Sets or retrieves whether multiple items in the list can be selected.

Inline	<SELECT MULTIPLE ... >
Script	select.multiple = bMultiple ]

false	Multiple items cannot be selected.
true	Multiple items may be selected.

This property returns or accepts only a boolean value, meaning true if set, and false if not. The property is read/write with a default value of false.

The following example shows the use of the MULTIPLE style attribute and the multiple object property to set the ability to choose multiple items in a list.

<select id=oSelect multiple>
   <option>Item 1</option>
   <option>Item 2</option>
   <option>Item 3</option>
</select>
...
<button onclick="oSelect.multiple=false">One</button>
<button onclick="oSelect.multiple=true">Many</button>
