{% hint style="info" %}
The `zindex` increases automatically, unless there's a connection to it.

The ISF inputs are defined as part of the `code` and will automatically become node properties, available to connect with and via the [Properties menu](/nodalin-docs/quick-guide/properties-menu.md) for manual adjusting.
