Questions fréquentes

How are arrays represented?

By default each array element gets a numeric segment, such as items.0.name. Empty arrays and objects are preserved as values.

Can I use a different separator?

The UI uses a dot separator. For custom separators, use the underlying library behavior in your own code.
