A composite user interface element can be assembled from plural
sub-elements. A simplified view of the representation of the user
interface element can be provided wherein the composited user interface
element appears to be a single element. When defined, various nodes for
representing the user interface can be designated as selectively
exposable. Such selectively exposable nodes can be ignored when
performing operations via the simplified view. Accordingly, programmers
can write code that need not take the complexity of the composite user
interface element into account. Property determination can be done in
light of the selectively exposable nodes. A simplified view can support
nested user interface elements having respective selectively exposable
nodes.
