 (require mrlib/hierlist) package: gui-lib

A hierarchical-list% control is a list of items, some of which can themselves be hierarchical lists. Each such sub-list has an arrow that the user can click to hide or show the sub-list’s items.

The list control supports the following default keystrokes:

    7.1 hierarchical-list%

    7.2 hierarchical-list-item<%>

    7.3 hierarchical-list-compound-item<%>

    7.4 Snips in a hierarchical-list% Instance
