Recently my site changed themes. The old theme had a built-in staff directory plugin with a specialized search that had two features we now miss:
It autocompleted staff member names.
It allowed you to select a staff specialty (i.e., custom post category) from a dropdown and display all members of that category.
How can I accomplish this in the new theme, with a staff directory plugin or otherwise? Currently, we have a staff directory plugin that adds staff members as a custom post type, and it includes a search function, but without these features. I would appreciate suggestions of plugins or code I can use.
