Thank you Asif!
Which content example number would that be?

I am trying to figure it out as well. I need to Spawn a secondary particle system per particle ID (from the source particles) based on an array.
Hope I am making sense.
That said I am looking at this node as it seems to do For Loop iteration.

So lets say Particle ID 0 = 0 particles spawned
Particle ID 1 = 5 particle spawned
Particle ID 2 = 2 Particles Spawned.
Something like this:

This one in ue4.27 they have two version of this same fx and one of them. Using map for node. I hope you will find this fx

Here it is. in the content example of ue4.27.
if you get any success with this node. please share that. thanks
