Expand and collapse

Summary  

In some areas of the BI applications, information can be shown in both condensed and expanded forms. For instance, in RAFT’s primary navigation (on the left of the screen), we allow users to expand and collapse menu items to browse the site hierarchy. In applications that include complex hierarchies, expanding and collapsing of those hierarchies is allowed.

Problem

...

Hierarchical information can be too long to show expanded at all times.

Solution

Rationale

...

We considered having this menu open at all times, but content proved to be overwhelming for readability or scanability.
