#1: Navigation Panel Folding
============================

Karabo GUI: Navigation Panel Folding
************************************

The former ``Navigation Panel`` now has two tab panels hosting the overall ``System Topology``
and the ``Device Topology``.

* The Device Topology fully obeys the ``Karabo Naming Convention`` (DOMAIN/TYPE/MEMBER)

The topology information is expanded by default. This means that all tree components are being
shown in the Navigation Panel resulting in a lengthy tree.
The ``header`` of both panels can be double-clicked to expand/collapse all components.

   Double-clicking the header (left) of the ``System Topology`` will collapse the tree,
   leaving a list of control hosts (right). Double-clicking it again will expand all tree items.

A tree component can be collapsed with its members being hidden from the list by
clicking the arrow icon besides it.

   A Karabo component with members (such as ``cppServer/doocs_1``) can be
   expanded (left) and collapsed (right) by clicking on the arrow icon besides it.
