Limit Google Maps Autocomplete to European boundaries

Question

I am using basic Google Maps autocomplete:

    function initAutocomplete() {
        autocomplete = new google.maps.places.Autocomplete(
                (document.getElementById('autocomplete_1')),
                {types: ['(cities)']});
        autocomplete.addListener('place_changed', fillInAddress);
    }

It works totally fine, but I want to LIMIT the RESULTS to only European places. I could do it with the component Region filter but it limits me to 5 countries. Europe has 20+ countries. How to limit?

Edit: European including the UK :)

Answer 1

Here is a wild guess I can do using the documentation :

function initialize() {
    var options = {
      bounds: myCustomEuropeBounds,
      strictBounds: true,
      types: ['(cities)']
     };

    new google.maps.places.Autocomplete(document.getElementById('autocomplete'), options);
}

The only thing left should be to define the bounds of Europe, which I let you find out by yourself :)

Hope it helped !
