I would like to display only to some users.
You can specify which user’s have the Biography Box suppressed via the plugin’s Exclusions tab; scroll down and you’ll see a section marked User Hiding Settings, but note that this only takes effect for single post or custom post types, not for archive pages or the front page.
I would like to display box above post title too, but I read and not undestand the support about that … Do you have some code that I can use? And how to put in the editor theme? Is it possible?
Yes, this is possible. But you will need to write some code to do this. The plugin works by appending or prepending the Biography Box to a post’s content. By the time the plugin’s code is called the post’s title has already been emitted by WordPress. What you’d need to do is to look at the templates in your theme, work out where the post title is handled and use one of the plugin’s template tags to emit the Biography Box. You’d need to disable the plugin automatically doing this in the settings as well as do this for each template you have.
It’s possible, but not trivial and certainly not a copy-and-paste exercise. How you’d go about this really depends on which theme you’re using and how that theme is structured. Most free themes follow a standard pattern for theme layout and structure but a lot of premium themes don’t.
