 @lancewillett:

 In [attachment:21562.no-jQuery.diff] the toggling works but currently
 without transition effects.

 CSS transitions do not work with the `display` property, which is why I
 went with `height` and `overflow:hidden;`. But they also need a specific
 hight value for them to work. It does not work with `height:auto;` (or
 `height:100%;` for that matter).

 Which brings us back to: ...calculating the height??
