I am creating a website for a doggie rescue, basically configuring the backend so they can manage dogs, volunteers, etc.
The legacy system had a feature where the user could start typing into an input field and all matching results would be displayed as you typed, most likely making ajax calls.
They would like to have this feature in WordPress. I tried using Admin Columns but you have to create the filter, modify the value and then click the Filter button and wait for it to load the results. I want to avoid the "click filter button and wait for page to come back with results" part.
One of the CPT that I am creating, volunteers, apparently has 40K records, and they would like to filter through them by using this "filter as you type" idea.
Is this possible from WPAdmin? I mean, adding a text input field that would filter all the posts using AJAX?
