Fifferent rendering portlets can interact with each other....

• Put a WCM menu component in one rendering portlet
• Put a WCM content item in another portlet.

To have the content item change when a different link is clicked in the menu, link the two portlets.

 

Broadcasting links

Rendering portlets can be configured to broadcast their current...

• state
• context

...to...

• Rendering portlets on the same page
• Rendering portlets on other pages

Information broadcast will only be received by rendering portlets configured to receive this information.

 

Receiving links

A rendering portlet can receive information on the state or context of WCM content items or components ...

• Displayed within it
• Displayed within other rendering portlets that are "broadcasting"

 

Example 1 - configuring links for a single portlet

In this scenario a single portlet is configured to display a component, such as a menu, that contains links to content. When the link is clicked the component will be replaced by the content of the link. The rendering portlet will then take on the behavior of the displayed content. The originally displayed component will not be displayed again until a new portal session is started.

Portlet content	Broadcast Links to:	Receive Links from:
Component	None	This portlet

When adding a component to a rendering portlet, you can also select an alternative presentation template in the content view of the content section. When a link is clicked in the component, the content that is then displayed will use the alternate presentation template.

 

Example 2 - configuring links for a menu and content

In this scenario...

• one portlet would contain a WCM Menu
• another portlet would contain some WCM content

Links would need to be created between the two portlets to enable the displayed content to change when a different links in the menu were selected.

Portlet content	Broadcast Links to:	Receive Links from:
Menu	This Page	None
Content	None	Other Portlets This Portlet

 

Example 3 - configuring links for a navigator and content

In this scenario...

• one portlet would contain a item views navigator
• another portlet would contain some WCM content

Links would need to be created between the two portlets to enable the displayed Content to change when a different links in the navigator were selected. The navigator would also change to reflect the current state of the content being displayed.

Portlet content	Broadcast Links to:	Receive Links from:
Navigator	This Page	Other Portlets This Portlet
Content	This Page	Other Portlets This Portlet
