Hierarchical List Box
Array type list boxes
This property specifies that the list box must be displayed in hierarchical form. In the JSON form, this feature is triggered when the dataSource property value is an array, i.e. a collection.
Additional options (Variable 1...10) are available when the Hierarchical List Box option is selected, corresponding to each dataSource array to use as break column. Each time a value is entered in a field, a new row is added. Up to 10 variables can be specified. These variables set the hierarchical levels to be displayed in the first column.
