Json Plugin and Tags How to use as Filter

Hi,

I use the json plugin so long without any tags, now I extended my interface with the two tag endpoints (tag-keys and tag-values).
For my understanding I should now be able to use those tag values to configure ad hoc filters. But how can I do this? I did not find any way to configure this.

Thanks,
Daniel

Ok I found out how to define (Create a vraibla for the Dashboard). Mow I can create the filter, but if I do this the page is freezing…
