<p><strong>Requires the plug-in <a href="https://wordpress.org/extend/plugins/advanced-custom-fields/" title="Awesome plug-in to manage custom fields" rel="ugc">Advanced Custom Fields</a>.</strong></p>
<p>This is a very basic add-on to allow the ability for relationship fields that are associated with a single related item, to be able to add a new<br />
item to the related item without leaving the post/page you are currently editing. Uses a colorbox pop-up to open the add new post window with very<br />
limited options.</p>
<p>Usage:</p>
<ul>
<li>Install the plug-in (standard WordPress installation)</li>
<li>Set up a relationship field with only one related item (standard Advanced Custom Field configuration)</li>
<li>Add or Edit a post with the relationship and the new Add New button will show up on the relationship field</li>
<li>Click the Add New button to open Colorbox add new post for the related item</li>
<li>Click the publish button and the new item will be added (or click the X button to cancel) and the Colorbox will close</li>
<li>The newly added item will be available for selection in the relationship list</li>
</ul>
