In WordPress administration I have 1800 users. When I want to publish a post, I have to choose the author out of the drop down menu (metaboxes author). This is very annoying.
I would like to be able to choose the author by typing her ID or username in a text input field.
Core's WordPress only has wp_dropdown_users()
to set the author.
Any idea how to do that ?
You can use the WebDevStudios Dynamic Dropdowns plugin, which does exactly what you asked for.
Currently you can download it only from GitHub: https://github.com/WebDevStudios/WDS-Dynamic-Dropdowns
