{{ $s = $s | append (slice "d" "e") }}
```
If a slice contains other slices, further slices will be appended as values:
```go-html-template
{{ $s := slice (slice "a" "b") (slice "c" "d") }}
{{ $s = $s | append (slice "e" "f") (slice "g" "h") }}
{{/* $s now contains a [][]string containing four slices: ["a" "b"], ["c" "d"], ["e" "f"], and ["g" "h"] */}}
```
The `append` function works for all types, including `Pages`.
