Add to a Drop-Down List

The wijinputmask widget allows you to create a mask for a drop-down list box. Use the showTrigger option to show the drop-down arrow and use the comboItems option to populate the drop-down list. See the InputMask > Drop Down sample of the MVC Control Explorer live demo at http://demo.componentone.com/ASPNET/MVCExplorer/inputmask/DropDown .

Create an ASP.NET MVC 5 Wijmo application.
In the Solution Explorer, expand the Views | Shared folder and double-click _Layout.cshtml to open the file.Add the following markup within the <body> tags of the page.
```
<input type="text" id="textbox1" />
      <h6>Mask</h6>
      <p>000-0000</p>
</div>
```

After the closing </div> tags you added in the previous step, enter the following jQuery script to initialize the wijinputmask widget and set the mask, comboItems, and showTrigger options. Using a zero as the masking element requires that a digit is entered. In this case, seven digits can be entered.

<script id="scriptInit" type="text/javascript">
    $(document).ready(function () {
        $("#textbox1").wijinputmask(
                {
                    mask: '000-0000',
                    comboItems: ['100-1000', '200-2000', '123-1234'],
                    showTrigger: true
                });
    });
      </script>

Press F5 to run the application. The showTrigger option displays the drop-down arrow. The mask requires digits in the format specified, and the drop-down list specified in the comboItems option contains three preset values.
