Hi Dan,
This explains it a bit, not the best example. A better example of it in action is the Google search engine. As you type data in, the results being displayed match what you are looking for. (In my version the results are a dropdown list below the text box. See Image) This way a user can use a text box as a way to search for and then submit information, right in one input field.
I am just wondering about the ability to do this with ajax and the API. I can picture it in a long round about resource intensive way, but I am hoping for something better.
I don’t think the /api/playlist/?search is what I am after.
