Hey,
First, you’ll need to add the “search with results” element to your page:
Then, you’ll need to update the “on change” workflow for when something gets typed in the input to hit the API you want to use with the REST API plugin:
Then, you’ll need to update the collection list containing all the results by binding it to the API’s results:
How to query the API and how the results will be displayed depend on which API you’re gonna use (all APIs are different, you’ll need to check their documentation).
Do you have any idea of which service you wanna use?
