This plug-in has been deprecated. However, you can still embed a tree on a Wordpress page by using the iframe embed in a Wordpress code block. Like this:

1. Create a code-block on your Wordpress page where you would like the tree to display.
2. Enter your embed code. Replace the tree ID with your tree ID:

<iframe width="100%" frameborder="0" seamless src="https://zingtree.com/deploy/tree.php?z=embed&tree_id=YOURTREEID">
</iframe>
<script type="text/javascript" src="https://zingtree.com/js/iframeResizerSmart.js"></script>
<script type="text/javascript">iFrameResize();</script>

Deprecated:

Zingtree has a WordPress plug-in, which you can download and install into WordPress to make it easy to include Zingtrees.

Usage Examples:

To embed a Zingtree into your web page, enter a short code like this with the ID of your tree:

[zingtree id="148196706"]

To make an orange button labeled "Popup Tree" , which displays your tree as a pop-up overlay on your page, do this:

[zingtree display="popup" id="148196706" button_text="Popup Tree" button_color="#EF6D23"]

To display in "panels" style and add persistent buttons to the bottom of each page:

[zingtree id="148196706" style="panels" persist_names="Restart|Submit Ticket" persist_node_ids="1|5"]

To hide the name of the tree and the back button, and show a real-time history of clicks::

[zingtree id="148196706" hide_title="yes" hide_back_button="yes" show_history="yes"]
