Remarks

From Microsoft Internet Explorer 5 to Internet Explorer 6, This element is a windowed control and does not support the z-index attribute or zIndex property.

As of Internet Explorer 7, this element is windowless and supports the z-index attribute and the zIndex property. The SELECT element does not require a strict doctype to enable windowless functionality.

This element is an inline element.

This element requires a closing tag.

Examples

This example uses the SELECT element to create a drop-down list box.

<select name="Cats" size="1">
<option value="1">Calico
<option value="2">Tortie
<option value="3" selected>Siamese
</select>

This example uses the select element to create a multi-select list box by setting the SIZE and MULTIPLE attributes. To retrieve the selected options for a multi-select list box, iterate through the options collection and check to see where SELECTED is set to true.

<select id="oSelect" name="Cars" size="3" multiple>
<option value="1" selected>BMW
<option value="2">Porsche
<option value="3" selected>Mercedes
</select>

This example adds a new option to the end of the SELECT list created above. The new Option constructor can also be used in Microsoft JScript.

<script language="JScript">
var oOption = document.createElement("OPTION");
oOption.text="Ferrari";
oOption.value="4";
oSelect.add(oOption);
</script>
