Options can be used to define a filter, classification criterion or conditioning on a node or a MetaTreeBranch as well as on a MetaAssociationEnd or query.

You can for example specify that a branch is only navigable if the user has selected in the Options window, from the Workspace object, the option 'Display of "All..." folders in the navigator'.

This navigation limit on option appears in the Properties window of the node or branch concerned.
