I put Google Map inside a div, and made a slideToggle onto the div. the Google Map doesn\'t display correctly.
You could wait until the map is loaded by adding an event listener for idle. This event will fire once the map is fully loaded and ready.
google.maps.event.addListenerOnce(map, 'idle', function() {
$('.hide').hide();
});
Here's the JSFiddle.
EDIT:
For anyone with a similar problem, here is the updated JSFiddle with the map positioned offscreen so it remains hidden without using display:none.
