## More Information

Certain fields can generate an excessive number of columns. For instance, a select field containing a list of countries will result in a separate column for each country when exported. The `wpforms_pro_admin_entries_export_allow_multiple_input_field` filter enables you to modify this behavior.

## Examples

#### All fields

```

/**
 * Filter to allow multiple input for specific fields.
 *
 * @link  https://wpforms.com/developers/wpforms_pro_admin_entries_export_allow_multiple_input_field/
 *
 * @param  bool    $allow      Default is true.
 * @param  array   $field      The field.
 *
 * @return bool
 */

add_filter('wpforms_pro_admin_entries_export_allow_multiple_input_field', '__return_false');
```

#### Specific field type

```

/**
 * Filter to allow multiple input for specific fields.
 *
 * @link  https://wpforms.com/developers/wpforms_pro_admin_entries_export_allow_multiple_input_field/
 *
 * @param  bool    $allow      Default is true.
 * @param  array   $field      The field.
 *
 * @return bool
 */

function wpf_disallow_multiple( $allow, $field ) {

  if ( $field[ 'type' ] === 'checkbox') {
    return false;
  }

  return $allow;
}

add_filter( 'wpforms_pro_admin_entries_export_allow_multiple_input_field', 'wpf_disallow_multiple', 10, 2 );
```

With this option enabled by default, any modifications to these fields that have already been exported will display **(modified)** in the column heading.
