Hi @v0rt3x

You can add some simple logic to test if the option has already been added like so:

<?php 

$added = array();
$args = array(
	'post_type' => 'locations',
	'posts_per_page' => -1,
	'meta_query' => array(
	         array(
			'key' => 'country',
		)
	),
);
$query = new WP_Query( $args );
					
if($query->have_posts()) : 
  echo "<select name='country' class='form-control' id='countryselect'>";
  while($query->have_posts()) : 
	$query->the_post();
	
	// get country
	$country = get_field('country');
	
	
	// bail early if this country has already been added
	if( in_array($country, $added) )
	{
		continue;
	}
	
	
	// add country
	$added[] = $country
	
	echo "<option>" . $country . "</option>";
  endwhile;
  echo "</select>";
endif;

 ?>

Hope that helps.

Thanks
