Dynamic Visualforce

Normally when a user visits a Visualforce page, Force.com constructs HTML or other content from the Visualforce components and their bindings to the controller. In contrast, dynamic Visualforce features allow the definition of the page itself, both its components and their bindings to the controller, to be determined at runtime, outside of the page. These features are most often used by software vendors who deliver Force.com applications on the Salesforce AppExchange, where the same application code must run within multiple, distinct customer organizations and adapt itself accordingly.

This section covers dynamic Visualforce features in more detail in the following subsections:

Dynamic field references—Dynamic field references allow the fields displayed in a Visualforce page to be injected into the page when viewed by a user. They can be provided by Apex code in the page controller or by Field Sets, a type of declarative metadata configurable without code.

Component generation—Visualforce pages can be constructed dynamically in Apex code. This can be essential for certain specialized user interfaces, but come with trade-offs not present with static pages.
