Name Type Supports EL? Description
binding String Only EL Identifies a backing bean property (of type UIComponent or appropriate subclass) to bind to this component instance. This value must be an EL expression.
id String Yes An identifier for this particular component instance within a component view.

The id must be unique within the scope of the tag's enclosing NamingContainer (eg h:form or f:subview). The id is not necessarily unique across all components in the current view

This value must be a static value, ie not change over the lifetime of a component. It cannot be defined via an EL expression; only a string is permitted.

rendered boolean Yes A boolean value that indicates whether this component should be rendered. Default value: true.
type String Yes The filter type: first|index. first: the first list value should evaluate to a Number or a value that can be parsed into an integer. index: A collection, array or comma-separated list of numbers. (Default: "first")
value Integer Yes The value valid for the type. If this evaluates to null, the first child will be rendered. If the type is "first", this value will be ignored, as "first" always renders the first rendered item. If the type is "index", the value must be a number.
