public class D2WQueryToManyRelationship

extends D2WQueryRelationship

The D2WQueryToManyRelationship class is a property-level component that builds a query based on the value for a particular key of a destination object of a to-many relationship. Since the component fetches all of the objects that can appear in the relationship, it is slower than the D2WQueryToManyField component.

You can specify whether the list is collapsible and whether the user interface is a browser or table of checkboxes. You can also specify the size of the browser or number of columns of checkboxes to display.

Property-level components are not accessed programmatically. Instead, you use the Web Assistant or Rule Editor to choose the property-level component that Direct to Web uses to display a property on a particular entity and task page.

If you want to create a property-level component to query based on a property, use D2WCustomQueryComponent.
