How to remove the "Powered by Google" logo in the Google Map Autocomplete dropdown list?

Animesh Nandi's answer is a bit old. Actually, to remove the 'powered by Google' logo I had to use the following code:

.pac-container:after {
    /* Disclaimer: not needed to show 'powered by Google' if also a Google Map is shown */

    background-image: none !important;
    height: 0px;
}

Check this out..

It is working in my app.

Place this in your stylesheet, and watch the magic.

.pac-container:after{ content:none !important; }

Our Autocomplete services do not need to be used in conjunction with a map, but it does require a “powered by Google” logo to appear under the text field if a map isn’t shown.
