Find the full list of field connections and parameters (Themer)
If you want to see a full list of field connections regardless of data type, the easiest way is to add an HTML module to your layout and then click the plus icon to the right of the text box.
In the screenshot above, you can see that text field connections like Post Title and Post Excerpt appear in the same list as Post Featured Image. The HTML module is a good way to find field connections and to try them out without worrying about the data type.
Many of the field connections have options. When you choose a field connection that has options, a settings box open, as shown in this screenshot for the Post Featured Image:
When you insert the field connection as a shortcode, you'll see how these settings are rendered as options in the shortcode. Using the same Post Featured Image example, the shortcode appears as follows:
[wpbb post:featured_image size='thumbnail' display='tag' align='default' linked='yes']
This is the easiest way to find shortcode options if you're using them to code your own layouts. There's also a shortcode index that you can use as a reference.
