Single Field for Lat, Long

Hello,

Currently, there isn't an option to use a single text field to paste Lat, Lng values for the map. You need to use two text fields: Lat and Lng.

Regarding the popup error, I don't see that issue on my demo site, screenshot https://imgur.com/LAfF0eE

When you change the pin on the map, the Lat and Lng values are updated. When you change the Lat and Lng values, the pin on the map is changed also. This feature is noted in the documentation https://docs.metabox.io/extensions/meta-box-geolocation/#two-way-data-binding

Hello,

I don't see you have an address field for the map field. Do you use the lat field as the address field?
Following the documentation https://docs.metabox.io/extensions/meta-box-geolocation/#address-field

Hello,

No, you should create a separate text field with the ID address_xxx to retrieve the suggestions address for the map. Here ist the sample code:

'fields' => [
    [
        'name' => __( 'Address', 'your-text-domain' ),
        'id'   => $prefix . 'address',
        'type' => 'text',
    ],
    [
        'name' => __( 'Lat', 'your-text-domain' ),
        'id'   => $prefix . 'lat',
        'type' => 'text',
    ],
    [
        'name' => __( 'Lng', 'your-text-domain' ),
        'id'   => $prefix . 'lng',
        'type' => 'text',
    ],
    [
        'name'          => __( 'Map', 'your-text-domain' ),
        'id'            => $prefix . 'map_v0mlzrv141',
        'type'          => 'map',
        'api_key'       => 'xxx',
        'address_field' => 'address',
    ],
]

Hello,

Please export your field group to a JSON file and share it here. I will check it on my demo site. Following the documentation https://docs.metabox.io/extensions/meta-box-builder/
