Scala, Akka-http - how to handle dynamic number of parameters?

I have a simple Akka routes:

    pathPrefix("api/games") {
      parameters("id".as[String].optional, "name".as[String].optional, "type".as[String].optional ...) { (id, name, type) => { 
       get {...}
     }
   }
 }

The problem is - I can have different number of optional parameters here. I do not want to pass all of them, because client can send different params. What is the best way to handle them dynamically (based on number of params) in akka-http?

I thought I can add all of them to list and check which are not None:

val params = List(id, name, type ...)

But I think it is very naive.

parameterMap may be helpful in your case. It extracts all parameters as Map[String, String]. Or parameterMultiMap if some parameter may repeat.
