server logic to determine which of the current navlist items is active. The
value will correspond to the value argument that is passed to
tabPanel().

of the navigation item that should be selected by default. If NULL,
the first navigation will be selected.
well
TRUE to place a well (gray rounded rectangle) around the
navigation list.
fluid
TRUE to use fluid layout; FALSE to use fixed
layout.
widths
Column withs of the navigation list and tabset content areas
respectively.
Details
You can include headers within the navlistPanel by including
plain text elements in the list. Versions of Shiny before 0.11 supported
separators with "------", but as of 0.11, separators were no longer
supported. This is because version 0.11 switched to Bootstrap 3, which
doesn't support separators.
