I am unsure if I simply misunderstood, but using the code you displayed first:
[[include :snippets:colalt |oddtop=[|show=+ show|hide=- hide]]
Like this…
[[include :snippets:colalt |eventop=[|hide=- hide]]
As many times as you want…
[[include :snippets:colalt |oddtop=[|show=+ show|hide=- hide]]
It can be folded.
[[include :snippets:colalt |oddend=[|nohide=true]]
[[include :snippets:colalt |evenend=[|show=+ show|nohide=true]]
[[include :snippets:colalt |oddend=[|nohide=tr
Completely bugs when on a page that that has the [[Module Rate]] Module.
It disables the module and then shows a bunch of CSS code on the page.
This could be a folly of my own. It wouldn't be the first time, but perhaps it's worth investigating.
