Adding multiple variable types in for_each in terraform?

Question

I want to add multiple ip addresses to configure access restrictions in azure for an app service and also this should be accomplished only for a few environments, I'm using the dynamic block to achieve this, it was working as long as there was only one IP, but now I want to allow more ip addresses, is there a way to achieve this?

dynamic "ip_restriction" {
  for_each = var.ip_addresses
   content {
     ip_address = ip_restriction.value["ip_address"]
     priority   = ip_restriction.value["priority"]
     name       = ip_restriction.value["name"]
   }
 }

This works perfect but I want to add the environment restriction as well. something like

for_each = var.env == "dev" || var.env == "qa" ? [1] : []

You are really close, you just need to change this array: [1] to be the actual array of IP addresses, like so:

for_each = var.env == "dev" || var.env == "qa" ? var.ip_addresses : []
