javascript - Google map markers - filtering based on category -

-

can show me example of displaying google map markers belong multiple categories , filtering these markers checkboxes - keeping in mind 1 marker may belong more 1 category?

i built map interface allows user filter markers category (with multiple categories per place).

from memory, categories stored data on each marker, , when category clicked markers iterated through create matching set. js in:
