The code below is for an action called ""{{headings}}"". It uses the css modification for the floating boxes suggested by DotMG (see bottom of this page). Use is "">>{{headings}}>>"" where it'll provide a list of headings on the page on the right hand side of the page. The exception to this is that any heading (such as a page title) with 6 "=" signs will not be on the list. Original code (before considerable modification) was from a suggestion at wikini for TOC code. 

Save the following code as ##actions/headings.php##...
%%(php)
<?php
/*
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ REVISED 12May05 (c) GMBowen to turn into a headings lister for the page. This modification +
+ ignores titles between 6 equal signs, removes the active links, etc. Released under GPL    +     
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Originally obtained from http://www.wikini.net/wakka.php?wiki=ActionSommaire on 11May05 as Table of 
Contents code

DotMG's suggestion for changing the css code (from WikkaCSS) is....
==min-width and max-width==
You should not use fixed width in .floatr and .floatl classes. Instead, I suggest the use of max-width and min-width :
%%(css).floatl {float: left; margin: 0.5%; padding: 0.5%; background: #EEE; min-width: 100px; max-width: 300px;}
.floatr {float: right; margin: 0.5%; padding: 0.5%; background: #EEE; min-width: 100px; max-width: 300px;}%%
	Try with the code ""<<{{calendar}}<< ""
