# Adding a Custom User Interface

You can create custom views using VDL, JavaScript and Tableau.

This introductory guide focuses on creating a custom user interface using two different methods, which includes using the View Designer. For more information about creating views using the JavaScript API, refer to the later section Using the JavaScript API to Create Custom Views.

The following sections provide a tutorial that creates a custom user interface using the graphical user interface provided by the View Designer, and introduces the code editor.

The View Designer generates the underlying VDL (View Definition Language, which is an extension of HTML) code. It is the default editor for a file with a `.vdl` extension when Xpress Workbench is initially installed—This setting can be changed in the project preferences.
