simplify multi layer view

[kartenkarsten]

It's quite common to show only features of a certian category selected by the user. Technical its possible to use one query for each category or maybe on for all and just show and hide some features by a certain tag.
(I would like to have such an example for fast adapting.)

What do you think is the best way to go?

I think this could possibly be solved by converting to use geojson as well. There is a filter function when adding geojson-layers that can be used to filter in advance.[1]

It does not enable live filtering though (only ahead of time), but there seem to be workarounds [2]

Or as a last option mapbox.js (which is built on top of leaflet) seems to be able to filter feaure layers (built from geojson) out of the box [3]
