[openspending-dev] Toggle between multiple years?

[Stefan Wehrmeyer]

Hi Adam,

bund.offenerhaushalt.de is currently a statically rendered (and partly broken) version of its former self. So there is no code powering it, just flat HTML files. The German OKF will try a relaunch at some point.

There is a new code version of Offenerhaushalt based on OpenSpending on GitHub:
https://github.com/openspending/offenerhaushalt.de
But this is not the same as the online version.

Cheers
Stefan
