Nov \'15 - still looking for a solution.
I\'m using the Google Picker API https://developers.google.com/picker/docs/#hiworld to (obviously!) have the user pick a fil
I had a similar problem and managed to solve it by using this css:
@media screen and (max-width: 991px) {
.picker.modal-dialog {
max-width: 355px !important;
}
.picker.modal-dialog-content.picker-dialog-content{
max-width: 355px !important;
}
}
You should be able to adjust the width and media query to suit your needs or do more media quires to make it look nicer in other devices.
I also set the option in the JS to the minimum PickerBuilder.setSize(566,350).
