Select
General
You need to use a fetchCallback
property to format the data of the API callback, which will match the data structure of the component.
Normal (Single selection and Multiple selection)
Single selection (automatically trigger request)
Single selection (manual trigger request)
Multiple selection (automatically trigger request)
Multiple selection (manual trigger request)

Click on the callback via option
Use the callback
attribute of the option.

Asynchronous requests are not executed by default
Set property firstRequestAutoExec
to false. The first asynchronous request is not executed (saving bandwidth and improving performance). Trigger the first asynchronous request when the options area is expanded.
