17.2 Navigation Panel and Navigation Header Formatting ¶

The overall display of navigation panels is controlled via this function reference, format_navigation_header:

Function Reference: $navigation_text format_navigation_header ($converter, \@buttons, $command_name, \%element) ¶

\@buttons is an array reference holding the specification of the buttons for the navigation panel (see Simple Navigation Panel Customization). \%element is the element in which the navigation header is formatted. $command_name is the associated command (sectioning command or @node). It may be undef for special output units.

The customization variable VERTICAL_HEAD_NAVIGATION should be relevant (see Customization of Navigation and Headers in Texinfo).

It may be undef for special elements. $vertical is true if the navigation panel should be vertical.
