apex:dynamicComponent
This tag acts as a placeholder for your dynamic Apex components. It has one required parameter—componentValue—which accepts the name of an Apex method that returns a dynamic component.
The following Visualforce components do not have dynamic Apex representations:
- <apex:attribute>
- <apex:component>
- <apex:componentBody>
- <apex:composition>
- <apex:define>
- <apex:dynamicComponent>
- <apex:include>
- <apex:insert>
- <apex:param>
- <apex:variable>
Example
1<apex:page controller="SimpleDynamicController">
2 <apex:dynamicComponent componentValue="{!dynamicDetail}" />
3</apex:page>

5/* Controller */
6public class SimpleDynamicController {

8 public Component.Apex.Detail getDynamicDetail() {
9 Component.Apex.Detail detail = new Component.Apex.Detail();
10 detail.expressions.subject = '{!acct.OwnerId}';
11 detail.relatedList = false;
12 detail.title = false;
13 return detail;
14 }

16 // Just return the first Account, for example purposes only
17 public Account acct {
18 get { return [SELECT Id, Name, OwnerId FROM Account LIMIT 1]; }
