Lip Gloss ships with a list rendering sub-package.
```go
import "github.com/charmbracelet/lipgloss/list"
```
Define a new list.
```go
l := list.New("A", "B", "C")
```
Print the list.
```go
fmt.Println(l)
// • A
// • B
// • C
```
<!--
Lists have the ability to nest.
```go
l := list.New(
"A", list.New("Artichoke"),
"B", list.New("Baking Flour", "Bananas", "Barley", "Bean Sprouts"),
"C", list.New("Cashew Apple", "Cashews", "Coconut Milk", "Curry Paste", "Currywurst"),
"D", list.New("Dill", "Dragonfruit", "Dried Shrimp"),
"E", list.New("Eggs"),
"F", list.New("Fish Cake", "Furikake"),
"J", list.New("Jicama"),
"K", list.New("Kohlrabi"),
"L", list.New("Leeks", "Lentils", "Licorice Root"),
)
```
Print the list.
```go
fmt.Println(l)
```

Lists can be customized via their enumeration function as well as using
`lipgloss.Style`s.
```go
enumeratorStyle := lipgloss.NewStyle().Foreground(lipgloss.Color("99")).MarginRight(1)
itemStyle := lipgloss.NewStyle().Foreground(lipgloss.Color("212")).MarginRight(1)
l := list.New(
"Glossier",
"Claire’s Boutique",
"Nyx",
"Mac",
"Milk",
).
Enumerator(list.Roman).
EnumeratorStyle(enumeratorStyle).
ItemStyle(itemStyle)
```
Print the list.

</p>
In addition to the predefined enumerators (`Arabic`, `Alphabet`, `Roman`, `Bullet`, `Tree`),
you may also define your own custom enumerator:
```go
var DuckDuckGooseEnumerator Enumerator = func(l *List, i int) string {
if l.At(i) == "Goose" {
return "Honk →"
}
return ""
}
```
Use it in a list:
```go
l := list.New("Duck", "Duck", "Duck", "Duck", "Goose", "Duck", "Duck")
l.Enumerator(DuckDuckGooseEnumerator)
```
Print the list:

</p>
If you need, you can also build lists incrementally:
```go
l := list.New()
for i := 0; i < repeat; i++ {
l.Item("Lip Gloss")
}
```
