UPDATE
So I’ve managed to display the repeater field as a select box with the following code
<select name="cars" id="cars">
<?php
// Check rows existexists.
// Loop through rows.
while( have_rows('yacht_type1') ) : the_row();
// Load sub field value.
$sub_value = get_sub_field('name');
// Do something...
echo '<option value="'.$sub_value.'">'.$sub_value.'</option>';
endwhile;
?>
</select>
Now what I’m actually searching for is how to get and store the value from the select box.
