---+!! Hierarchical Navigation

*Navigation block that displays the current topic, its parent and children (if any).* %BR%
This is intended to be included in other topics, for example in a side navigation bar (WebLeftBar).

_NOTE: The lookup for parent and children will increase the loading time of your pages._

%TOC%

---++ Usage
Two sections are defined:
   * =all=
   * =children=
   
---+++ Displaying the Parent - Current - Children block
<blockquote>
<verbatim>
%INCLUDE{"%TWIKIWEB%.HierarchicalNavigation" section="all"}%
</verbatim>
</blockquote>
generates:

%INCLUDE{"%TWIKIWEB%.HierarchicalNavigation" section="all"}%


When included in WebLeftBar (using default Pattern skin) this is styled to:

<div id="patternLeftBarContents">
%INCLUDE{"%TWIKIWEB%.HierarchicalNavigation" section="all"}%
</div>

---+++ Displaying child topics
<blockquote>
<verbatim>
*Child topics:*
%INCLUDE{"%TWIKIWEB%.HierarchicalNavigation" section="children"}%
</verbatim>
</blockquote>
generates:

*Child topics:*
%INCLUDE{"%TWIKIWEB%.HierarchicalNavigation" section="children"}%
