Popup overlays allow you to use a button to launch a tree from your web site. Rather than embedding a tree into a page, you can include a button that launches a tree in a pop-up overlay.

See a demonstration here.

Here's how to make a pop-up overlay:

1. In the editor, open the tree that you would like to embed.
2. Click Publishing and then select Publishing Links.  
3. Click Customers External Use, Display as a Pop-up Overlay. 
4. Copy the default button code to your website. IMPORTANT: There are two separate pieces of code needed.

 
Note: You can choose different button colors and button text via the Advanced options.
