Love this suggest field. For some reason, I can't get the placeholder option to work when I have either explicit options set or am using content mode. If I clear all options, I see the placeholder, but not otherwise. Here's my code:
link: display: Related Project placeholder: "Please select a project" instructions: For linking image type: suggest max_items: 1 content: folder: projects label: title value: url
Here you can see it shows the first project, even before I choose one. I would expect the placeholder to appear here.
And when I have no options set at all, rendering the field useless, the placeholder shows up:
