Currently, in Mirage2, the community-list page only allows the user to expand a single path in the tree at a time, i.e. expanding a community and then expanding a sibling community will automatically collapse the previously open community. In addition, the currently expanded comm/coll's name is bolded.
It may be useful for users to be able to expand more than one path at a time. This feature introduces this configuration (defaulting to the current behavior) and implementation. Do note, with this mode enabled, comm/coll names are no longer bolded. This feature also adds links for Expand/Collapse All
