In this video, we create modules and nodes, use different field types (text, image, selectboxes, radiobuttons etc.), and connect nodes together by using one node as a source for field values.

First, we create a module by clicking "Add module". A module itself doesn’t contain any fields, it's just a structural element that organizes nodes with real data and appears as a section in the project menu. Next, we add a child node by clicking "Add sub-node".

Within the added node, we create several fields of different types by clicking "Add field". Simple types like text or image don't require additional parameters. Fields with options (like radiobutton, selectbox or multiselect) need to define where the options come from. The available options can be fixed values (then you need to add them one by one) or taken dynamically from another node in the the structure, making the system flexible and extendable.

For cases with many possible options, it’s practical to create a separate node to store the choices. The field can then reference this node as its source, so any new options added will automatically become available in the selection field. This approach keeps technical data organized and allows the system to grow without redesigning the structure.

In the video we applied it in practice. We created a simple real estate register, where values for the property type selectbox (like house or apartment) come from a separate node.
