I am using a custom field of type "Post". I am using it to hold multiple posts references.
As a field type, I am using the Checkbox list.
The problem that I am facing is that I do not know how can I modify option labels so that I can include other fields data. Right now post title is being shown with each box.
My second question is that how can I add data-attributes to each list element.
I am stuck, any help will be greatly appreciated. Thanks!
But there is no filter hook to add data attributes to each list element. You can create your own custom field type by following this documentation https://docs.metabox.io/custom-field-type/
.
