Create form to abstract class based on children attributes

[maurodlt]

Is your feature request related to a problem?

I am currently modeling publications using an abstract class Publication with concrete subclasses such as Journal and Conference. However, the web editor does not support creating instances of abstract classes in a flexible way.

As a result:

• There is no single, unified entry point for adding a publication.
• The UI cannot dynamically adapt to the specific attributes required by different publication types.

This makes the publication creation process error-prone, redundant, and harder to extend when new publication types are introduced.

Describe the solution you'd like

Introduce a generic “Add Publication” page in the web editor that is linked to the abstract Publication class.

The proposed behavior is:

1. The page initially presents the user with a dropdown or selection list of available concrete subclasses (e.g., Journal, Conference, …).

2. Once a subclass is selected:

• The form dynamically updates to display only the attributes relevant to that subclass.

• Shared attributes defined in Publication (e.g., title, year, authors) are always shown.

• Subclass-specific attributes (e.g., journal name, volume, issue, or conference location, proceedings) are conditionally displayed.

3. On submission: The correct subclass instance is created and persisted.
