@zeesh49 Under filter out you mean to made elements not contain instances of ElseWhenEntrySelector?
Then

fun CodeBuilder.append(elements: Collection<Element>, separator: String, prefix: String = "", suffix: String = ""): CodeBuilder {
    return buildList(elements.filter { !it.isEmpty }.filterNot { it is ElseWhenEntrySelector }.map { { append(it) } }, separator, prefix, suffix)
}
