There're two possible attributes for lists, although only one applies to numbered and non-numbered lists whereas the other only applies to non-numbered lists.

Bullet (only for non-numbered lists)

The Bullet property allows you to change the bullet in your list with any kind of string, even emoji. Just enter any kind of bullet you can think of. If you'd enter 🐢 turtle emoji, you'd have a turtle bullet (#thebestbullet).

List Animation

The other list property allows you to define how the separate list entries are animating in - if they should even animate in, or if the whole list should appear at once.

This is split up into two different properties:

Animation Duration

You can set how long it should take for a line to appear (if All lines appear at once is disabled)

All lines appear at once

This attribute tells Hypderdeck that all elements in the list should appear at once. The alternative (and default) is a list where one element appears after the other.
