What are the steps to transform an HTML select element into a sub-menu user interface?

Can the native HTML element select be used to add submenus?

  • Processes
    • lack of process
    • failure to follow process

HTML

<!DOCTYPE html>
<html>
<body>

<select>
  <optgroup label="Swedish Cars">
    <option value="volvo">Volvo</option>
    <option value="saab">Saab</option>
  </optgroup>
  <optgroup label="German Cars">
    <option value="mercedes">Mercedes</option>
    <option value="audi">Audi</option>
  </optgroup>
</select>

</body>
</html>

The code above only allows for defining sub-sections, but is there a way to create separate menus UI within the parent UI? Any suggestions on how this can be achieved would be greatly appreciated.

Thank you.

Answer №1

Unfortunately, standard select menus do not support sub-menus. However, there are some easy jQuery solutions available that involve using unordered lists.

Here are two simple and effective solutions:

Answer №2

One way to achieve this is by utilizing jQuery instead of native HTML.

<Select id="cartype">
    <option value="Select">Select Car Type</option>
    <option value="Swedish Cars">Swedish Cars</option>
    <option value="German Cars">German Cars</option>
</Select>
<select id="carDetail">
    <option value="unset">Select Car Type First</option>
</select>

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
$(document).ready( function () {
    $.fn.addOption = function(optText, optValue){
        var option = new Option(optText, optValue);
        return this.append(option);
        };
    $("#cartype").change(function() {
        $("#carDetail option").remove();
        switch ($("#cartype").val())
        {
        case "Swedish Cars":
            $("#carDetail").addOption("Volvo", "volvo");
            $("#carDetail").addOption("Saab", "saab");
            break;
        case "German Cars":
            $("#carDetail").addOption("Mercedes","mercedes");
            $("#carDetail").addOption("Audi","audi");
            break;
        default:
            $("#carDetail").addOption("Select Car Type First","unset");
        }
    });
});
</script>
