KBTree (subclass of KBLinkTree)

Tree Grouping (group)

This is a list of comma-separated expression (each of which should be a valid expresion in an SQL select query) which are used to group items up to generate the tree.

Open on click (clickopen)

If set then clicking on an item, as well as selecting that item, expands that branch of the tree.

Close on Set (setclose)

The tree control always expands the branch in which contains the current value. Setting the close on set option closes all other branches when the value is set.

Tree type (treetype)

The tree control can either display expanded in which case values appear as leaves in the tree, or flattened, where leaves and branches are merged. The former is probably more intuitive; the latter is more compact. Shallow is like expanded, except that the tree does not have to be full depth; read the manual for details.
