This should get you on the right track, just modify the echo to make a button:
<?php
$full_object = get_field_object('field_name_here');
foreach($full_object['value'] as $value){
// $value is the 'value'
$label = $full_object['choices'][$value];
} ?>
Try this:
<?php
$full_object = get_field_object('field_name_here');
foreach($full_object['value'] as $value){
// $value is the 'value'
$label = $full_object['choices'][$value];
} ?>
This is generally caused by responsive designs setting max width 100% on all images.
Try this on whatever the wrapper div is that holds the map:
.map-wrapper img{
max-width:none !important;
}
That will make sure that map images (and only map images) aren’t distorted.
