   Example

   Using did_action() function to make sure custom meta field is only added during the first run since it can run multiple times.

   
   function my_sticky_option() 
   {
   	global $post;
   
   	// if the post is a custom post type and only during the first execution of the action quick_edit_custom_box
   	if ( $post->post_type == 'custom_post_type' && did_action( 'quick_edit_custom_box' ) === 1 ) 
   	{ 
   ?>
   
   	<fieldset class="inline-edit-col-right">
   		<div class="inline-edit-col">
   			<label class="alignleft">
   				<input type="checkbox" name="sticky" value="sticky" />
   				<span class="checkbox-title">
   					<?php _e( 'Featured (sticky)', 'textdomain_string' ); ?>
   				</span>
   			</label>
   		</div>
   	</fieldset>
   <?php
   	} // endif;
   }
   // add the sticky option to the quick edit area
   add_action( 'quick_edit_custom_box', 'my_sticky_option' );
