Defining Container Restrictions

Optionally, you can limit the content types that can be dropped on a container for layouts used in Web Page Composer (WPC). To do this, define restrictions for this container using the allowedDropTags attribute in the portalapp.xml file. This attribute contains a multivalue comma-separated list of the content types that can be dropped on this container. When a content item, such as an iView or page, is dropped on a container, the page builder compares the allowedDropTags attribute of the container with the com.sap.portal.ContentTemplate attribute of the item.

To define restrictions, add this attribute to the XML_Template property used by Ajax Page Builder, for example:

               <Container containerID="com.sap.portal.reserved.layout.Cont3">
        <TableCellData width="50%" height="100%" colSpan="1" vAlign="top"/>
        <ContainerBehaviors allowedDropTags="iview,wpc_weblinklist"/>
        </Container>
</ContainersRow>

To support Accessible Area Management in WPC, which is running in Portal Runtime (PRT) Page Builder, define container restrictions in portalapp.xml, for example:

               <property name="com.sap.portal.reserved.layout.Cont1" value="left">
        <property name="title" value="Left Column"/>
        <property name="orientation" value="vertical"/>
        <property name="allowedDropTags" value="iview,wpc_weblinklist"/
</property>
