1 -/* ===========================================================================
2 - Alder Support Center - article accordion
3 - Goes in an XWiki.JavaScriptExtension object on AlderTheme.Scripts (alder wiki).
4 -
5 - Turns each top-level H2 inside #xwikicontent into a collapsible section, so a
6 - long omnibus article becomes a short list of section titles. No article needs
7 - editing: the sections come from headings the content already has.
8 -
9 - Deliberate behaviours, all reversible by disabling this object:
10 - * Sections open independently. Opening one does not close another.
11 - * The first section starts open, so the page never looks empty.
12 - * Fewer than two H2s: nothing happens, the article renders normally.
13 - * Edit/preview modes are skipped, or authors would be editing generated
14 - markup.
15 - * A link to a heading inside a collapsed section opens that section and
16 - scrolls to it, including on first load and on later hash changes.
