Add a custom dropdown menu in quick edit

Hi, everybody, i’ve been trying to get the “custom field” options in a dropdown menu with no success, i work with this tutorial but my php coding knowledge is limited. Could you give a hand?

This is the original code:

// Add to our admin_init function
add_action('quick_edit_custom_box',  'pde_add_quick_edit', 10, 2);

function pde_add_quick_edit($column_name, $post_type) {
	if ($column_name != 'estatus_column') return;
	?>
    <fieldset class="inline-edit-col-left">
	<div class="inline-edit-col">
		<span class="title">Estatus del lote:</span>
		<input type="hidden" name="pde_widget_set_noncename" id="pde_widget_set_noncename" value="" />
		<?php // Get all widget sets
			$estatus_columns = get_posts( array(
							'post_type' => 'lotes',
							'numberposts' => -1,
							'post_status' => 'publish') );
		?>
		<select name='post_widget_set' id='post_widget_set'>
			<option class='widget-option' value='0'>Elija un estado nuevo</option>
			<?php
			foreach ($estatus_columns as $estatus_column) {
				echo "<option class='widget-option' value='{$estatus_column->ID}'>{$estatus_column->post_title}</option>\n";
			}
		        ?>
		</select>
	</div>
    </fieldset>
	<?php
}

I need get the “estatus” custom field and show it in quick edit instead the post->ID and post_title (in a option element).

Thank you in advance, i’ve been searching, trying, smashing my head with no one solution.
