This section explains briefly about how to create a dropdownlist in your application with JavaScript.
Essential JavaScript dropdownlist provides support for multiple selections, within your web page and allows you to specify an option from the list.
The following screenshot demonstrates the functionality with dropdownlist action.
For getting started you can use the ‘ej.mobile.all.min.js’ file, which encapsulates all the ‘ejm’ controls and frameworks in one single file.
For themes, you can use the ‘ej.mobile.all.min.css’ CDN link from the snippet given. To add the themes in your application, please refer this link.
