-Ewiki nav bar plugin - by AndyFundinger
-
-this plugin will create a navigation bar from a site map on a page. The site
-map should be a list with wiki words or [] style wiki links. You must select
-two functions to control the operation of your navigation bar.
-$ewiki_plugins['select_navbar_buttons'][0] will be run to determine which
-buttons are invisible($NavBar[$id][2] = 0), visible($NavBar[$id][2] = 1), or
-active ($NavBar[$id][2] = 2). $ewiki_plugins['render_navbar_section'][0] will
-control the actual rendering and is designed to support recursive calls. Two
-versions of each are supported. You can also create your own site specific
-selector or renderer. I use a function that calls
-ewiki_navbar_selectall_buttons() to select the level 1 pages and then
-ewiki_navbar_select_psuc() to select parents, siblings, uncles, and children if
-possible.
-
-The effect of this NavBar relies on stylesheets. You must add several classes
-to make the NavBar appear properly. An example style sheet is
-WikiNavBarStyle.css. The following tag will add this example style sheet to your
-code:
-
-<link rel='stylesheet' href='./fragments/WikiNavBarStyle.css' type='text/css' media='all' />
-
-The NavBar array is composed of one line per button as follows:
-$NavBar[]=array( line text, depth, activation,target page);
-
-Call mkLiveWebNavBar() from within your page to create a NavBar.
