I tried this new Zone lookup app and this seems to be great simple app for many cases.
My app works fine except i have one problem. When I click map, application shows selected zone and hides other (as I want it to work) but how can I clear the selection? When I have written address, then I can simply click 'x' end of address and then it clears the selection and I see all zones. How can I do the same when clicking map (some other way than refreshing page).
