Can I reduce the loop inside my method with map or is there a shorter implementation of this code that's dropping elements in sequence?

// Method that drops one element in sequence
def drop_Val_In_List[String](ls: Seq[String], value: String):  Seq[String] = {
    val index = ls.indexOf(value)  //index is -1 if there is no matc
    if (index < 0) {
        ls
    } else if (index == 0) {
        ls.tail
    } else {
        // splitAt keeps the matching element in the second group
        val (a, b) = ls.splitAt(index)
        a ++ b.tail
    }
}

val KeepCols = Seq("id", "type", "month", "car", "road")


// Generalization of the above method to drop multiple elements
def drop_Val_List_In_List[String](ls: Seq[String], in_ls: Seq[String]): Seq[String] = {
    var tmp_ = ls
    //println(tmp.getClass)
    for(x <- in_ls ){ // should work without var x
        tmp_ = drop_Val_In_List(tmp_, x)
    }
    tmp_;
}

val tmp = drop_Val_List_In_List(KeepCols, List("id", "type", "month"))
```
