Simple Dynamic Component:

Simple Dynamic Component:
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.

public class SimpleDynamicController {

    public Component.Apex.Detail getDynamicDetail() {
        Component.Apex.Detail detail = new Component.Apex.Detail();
        detail.expressions.subject = '{!acct.OwnerId}';
        detail.relatedList = false;
        detail.title = false;
        return detail;
    }

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