Standards information

Document Object Model (DOM) Level 2 HTML Specification, Section 1.6.5
HTML 4.01 Specification, Section 17.6

Remarks

Microsoft Edge introduces updates to the select control that makes it more interoperable with other browsers. These updates include control and options styling improvements, like support for display: none for options.

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

As of Windows 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.

Examples

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


<!DOCTYPE html>

<html>
<head>
  <meta charset="utf-8" />
  <title>select</title>
</head>
<body>
  <select name="Cats" size="1">
    <option value="1">Calico</option>
    <option value="2">Tortie</option>
    <option value="3" selected>Siamese</option>
  </select>
</body>
</html>

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.


<!DOCTYPE html>

<html>
<head>
  <meta charset="utf-8" />
  <title>select</title>
</head>
<body>
  <select id="oSelect" name="Cars" size="3" multiple>
    <option value="1" selected>BMW</option>
    <option value="2">Porsche</option>
    <option value="3" selected>Mercedes</option>
  </select>
</body>
</html>

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


<!DOCTYPE html>

<html>
<head>
  <meta charset="utf-8" />
  <title>select</title>
</head>
<body>
  <select id="oSelect" name="Cars" multiple>
    <option value="1" selected>BMW</option>
    <option value="2">Porsche</option>
    <option value="3" selected>Mercedes</option>
  </select>
  <script>
    var oOption = document.createElement("option");

    oOption.innerText = "Ferrari"; // Using innerText for backwards compatibility.
    oOption.value = "4";

    document.getElementById('oSelect').appendChild(oOption);
  </script>
</body>
