Dynamically populating a repeater SELECT field

Hi

I have a repeater field (boats_due) with a sub field SELECT (boat_due) in there. I would like to populate this subfield select (boat_due) with the value of a textarea in an options panel (boat_due_names).

As the SELECT is a sub field within a repeater field that I need to populate, I am a little lost from the docs how to do this?

I have tried the below.

Thanks

function acf_load_field( $field ) {
	
	// if has rows
	if( have_rows('boats_due', 'option') ) {
        
    // while has rows
     while( have_rows('boats_due', 'option') ) {
		 
		 // instantiate row
            the_row();
		 
		 // reset boat due
    		$field['boat_due'] = array();
		 
		 // vars
            $value = get_sub_field('boat_due');
	 }
	}
    
    // get the textarea value from options page without any formatting
    $choices = get_field('boats_due_names', 'option', false);

    
    // explode the value so that each line is a new array piece
    $choices = explode("\n", $choices);

    
    // remove any unwanted white space
    $choices = array_map('trim', $choices);

    
    // loop through array and add to field 'boat due'
    if( is_array($choices) ) {
        
        foreach( $choices as $choice ) {
            
            $field['boat_due'][ $choice ] = $choice;
            
        }
        
    }
    

    // return the field
    return $field;
    
}

add_filter('acf/load_field/name=boat_due', 'acf_load_field');
