Details

PaneSelector([True -> a, False -> b], Dynamic(test)) lowers to it. The panes are key -> pane rules and the selector is the binding Dynamic(test), as Wolfram boxes it; the pane drawn is the one whose key reads the same as its value (True, 1, a name). A value with no pane draws nothing. The example's expected shows Tuple: compute-engine reads a symbol-keyed pair as one.
A writer with no values (LaTeX, text, a terminal) writes the first pane.
It is its own element: it follows the page's variables without its parent. A phrase that appears only under a condition is a pane under True alone.

Examples

Basic #

a box is inert: it evaluates to itself, its rules kept as rules

\mathrm{PaneSelectorBox}(\bigl\lbrack\mathrm{Rule}(\text{1}, \text{one}), \mathrm{Rule}(\text{2}, \text{two})\bigr\rbrack, \mathrm{Dynamic}(n))

Out

\mathrm{PaneSelectorBox}(\bigl\lbrack\mathrm{Rule}(\text{1}, \text{one}), \mathrm{Rule}(\text{2}, \text{two})\bigr\rbrack, \mathrm{Dynamic}(n))
