The DDSList is a frequently-used user interface control for Mobile RPG. It has four distinct “personalities”:

  1. A navigation list (which provides a scrolling list with lots of options).
  2. A radiobutton list (which provides a radiobutton list that accepts multiple choices).
  3. A checkbox list (which provides a checkbox list that accepts one choice).
  4. A dropdown list (which provides a single-select dropdown)

This article discusses how to use the DDSList control to provide a dropdown element for a Mobile RPG record format. When rendered this way, the runtime HTML is a select tag with option tags for each item in the dropdown list. This article’s example code is shown below in Figure 1a.
