Description

A tree being used to gather selections does not provide visible affordances that selections are possible; the current approach is to show selected nodes in bold. Outside of the change in the mouse-over cursor, there's no indication that nodes may be selected.

A proper affordance would meet user expectations: a checkbox that is either checked or unchecked. This can be "simulated" using CSS background images and margins, or the client-side JavaScript could create actual checkbox elements.
