  I’m trying to find a way to get the title in a repeater to be used as a select. I tried the example on one of the documentation but the select is empty:

  	function acf_load_color_field_choices( $field ) {
      
  		// reset choices
  		$field['choices'] = array();
  		
  		
  		// get the textarea value from options page without any formatting
  		$choices = get_field('playlist_title', 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 'choices'
  		if( is_array($choices) ) {
  			
  			foreach( $choices as $choice ) {
  				
  				$field['choices'][ $choice ] = $choice;
  				
  			}
  			
  		}
  		
  	
  		// return the field
  		return $field;
  		
  	}
  	
  	add_filter('acf/load_field/name=color', 'acf_load_color_field_choices');

  I was able to list all text fields with playlist_title using this code:

  <?php
  				// check for rows (parent repeater)
  				if( have_rows('media_playlist') ): ?>
  					<?php 
  					// loop through rows (parent repeater)
  					while( have_rows('media_playlist') ): the_row(); ?>
  							<?php the_sub_field('playlist_title'); ?>
  					<?php endwhile; // while( has_sub_field('to-do_lists') ): ?>
  				<?php endif; // if( get_field('to-do_lists') ): ?>

  Thanks for the help.

  So I tried using this solution from https://support.advancedcustomfields.com/forums/topic/return-all-values-from-a-repeater-row-by-using-a-single-dynamic-select/ and it deletes the select field and adds two random blank fields

  function acf_load_contact_field_choices( $field ) {
      
  		// reset choices
  		$field['choices'] = array();
  	
  		// if has rows
  		if( have_rows('media_playlist') ) {
  			// while has rows
  			while( have_rows('media_playlist') ) {
  				// instantiate row
  				the_row();
  				
  				// vars
  				$contactName = the_sub_field('playlist_title');
  	
  				// append to choices
  				$field['choices'][ $contactName ] = $contactName;
  			}
  		}
  	
  		// return the field
  		return $field;
  		
  	}
  	add_filter('acf/load_field/name=color', 'acf_load_color_field_choices');

  The filters you are trying to use modify the choices of fields in the admin. They will not create a select field for you.

  
  if (have_rows('your-repeater')) {
    ?>
      <select>
        <?php 
          while (have_rows('your-repeater')) {
            the_row();
            ?><option value="<?php the_sub_field('your-sub-field'); ?>"><?php the_sub_field('your-sub-field'); ?></option><?php 
          }
        ?>
      </select>
    <?php 
  }
