8.11.1 Order By Item Sort Example

View an Order By Item sort example.

Configuring an Order By Item enables end users to choose region ordering from a set of predefined options. Including an Order by Item is particularly useful for region types which do not support ordering on their own, such as a Cards region. Order By Item is supported by all region types except map regions, tree regions, interactive reports, and interactive grids.

An Order By Item configuration consists of predefined order by clauses which are maintained at the region level and a page item which is available to end users at runtime. While the default page item is a Select List, other item types, such as radio groups, plug-in based types or even hidden items, are also supported.

The following example shows a cards region. An Order By select list displays above the cards and contains the options: Salary descending, Salary ascending, Department and Salary, and Employee Name.
