Re: Adding such a feature [additional drop downs] would require custom development.
I think I must have misunderstood – when you first responded to this question, you said it would require custom development and additional plugins. I took this to mean that if I downloaded the plugins specified and added the additional field using the method you suggested, I could add the additional drop down. I have followed your instructions closely, with the hope that once I added that field properly, you would be able to explain how to add the drop down.
Re: Make sure the edit the correct template file.
As per instructions on this page I was not editing the plugin’s template file, but rather editing a copy of that file, which is located in the new folder I created, located at “wp-content/connections-templates/gridder/” – is this the correct location? I moved the text to the appropriate lines in the card-single.php file and the card.php file. I have been using <?php and ?> tags — you mentioned using “<php” without the question mark, so that could be an issue. I wasn’t able to find the appropriate CSS elements to change using the inspector, because the field isn’t currently displaying, so that could be the issue? I am using the same ID for the field in both the php files and the Code Snippet, but maybe I am confused about what the instructions mean by “Field id”? I’ve attached photos of the Code Snippet I added and the code I added in the php. Hopefully this illumintes something.
Again, thank you so much for your help in getting this off the ground.
