Its not so much a "method" that it supports, but rather that you need to supply it an array. Each member of the array is then used to spawn a new event.

Im curious if theres another JavaScript method other than split() you could use in the "Source field expression".

You can supply any JS there that results in an array. That could be a field that is an array, or it could be a method calling a field that results in an array (like split())

Can you think of another method other than split? I was hoping to get an example, with the data structure.

I think were going about this from the wrong angle. What does your data look like, and what are you trying to do with it?

Im just curious – searching for information.

i see what you did there
