A common requirement in many mobile data storage and management applications is to display cascading data in a List control (such as a list of menu choices). Some of the items in the List will have sub-choices. When an item in the List that has sub-choices is selected, the List is repopulated with the sub-choices and a 'back' button is enabled to go back to the previous level.
There is no limit as to how deep this hierarchy of nested Lists can be. Typically, when an item in the List that has no sub-choices is selected, an action associated with that List item is executed.
Alpha Anywhere is a rapid app development platform that makes integration and database management features easy to build. In the videos below, we show how with Alpha Anywhere you can use a List to display an hierarchical menu system. We show how a genie can help you generate the JSON data for the hierarchical menu system and how the List's 'Quick Setup Genie' can be used to configure the List to display the nested Lists defined by the List's JSON data.
