Questions tagged [visualforce-component]
Visualforce components encapsulate a common design pattern and can be reused several times in one or more Visualforce pages. Salesforce provides a library of standard, pre-built components, such as <apex:relatedList> and <apex:dataTable>, that can be used to develop Visualforce pages. In addition, you can build your own custom components to augment this library.
