In an insurance claims application, you want to capture miscellaneous inventory items, as displayed in the screen below.
A miscellaneous item has a name and value, and is defined as a data type. You want to store the data entered in a property called .Items. Which property type should .Items be?
The appropriate property type for .Items should be 'Page List'. In this scenario, each miscellaneous item consists of a name and a value, making it a complex data type with multiple properties. A 'Page List' property type is suitable for storing a list of such complex structures, where each item in the list is a separate page (record) that can hold multiple properties such as 'Item Name' and 'Value of the Insured Items'.
