public abstract class GridComponent
extends StructuredBaseTag

An abstract base class for all tags that can be contained directly inside of a Grid tag. This class provides services to subclasses such as methods to access:

• the grid's current render state
• the Grid tag itself
• the Grid tag's GridContext

Additionally, the requirement that any subclass be parented by a Grid is enforced here.
