Do I still need the additional Fields plugin in GLPI 11? The Genericity clarification

A few weeks after the GLPI 11 release, numerous questions arose within the community. Teclib’s GLPI editor is doing an amazing job, especially with the content generated by Arthur Schaefer, the GLPI prophet. However, this new release is huge, featuring many new enhancements.

To continue deserving the Best Communication GLPI Award in 2026, we aim to contribute to this effort by launching a new series of articles that explore recurring questions and features often overlooked or not immediately apparent.

Ever since the October 1st release, a question has consistently been on the minds, forums, and chats with our users:

Does the powerful new Genericity feature mean we can finally drop the Additional Fields plugin?

It’s a great question, as GLPI 11 delivers native tools for asset customisation: Genericity. The short answer is: Yes, for certain tasks, the Additional Fields plugin remains a vital and necessary component of your asset management workflow.

Here is my clarification to understand how the new Genericity feature and the existing Additional Fields plugin in GLPI 11 work along.

Case 1: Creating brand new asset types (Asset definition)

The new Genericity feature in GLPI 11 empowers you to create entirely new, custom asset categories from scratch—assets not inherently built into the core GLPI system.

When you use Genericity to create a new asset under Setup > Asset definitions, such as a Projector, Aeroplane, or Superhero, you have the necessary fields and properties natively within GLPI.

The result? For any asset type created using the Genericity feature, you DO NOT need the Additional Fields plugin to manage or extend its field set. All customisation is handled natively, simplifying configuration and long-term maintenance.

Superheroes’ fields are entirely GLPI native. Well, not entirely! I’ve just created the Superpowers multiple dropdown without needing any additional plugin.

So, again, for newly generated assets you don’t need the additional fields plugin.

Case 2: Customising existing core assets (Fields plugin still required)

GLPI has always provided core, built-in asset types like Computers, Contracts, Monitors, Tickets, and Users. These core objects rely on the application’s original structure.

If your goal is to add a new, custom field to an existing, built-in asset type—for example, adding a custom field to the standard Computer or Contract form—the new Genericity feature cannot be used for this purpose.

In the example, I’ve created a mandatory Additional Field named Code for my tickets (bottom right)

The result? To extend or modify the field set of any existing core asset types, you will still need to use the powerful and reliable Additional Fields plugin. The plugin provides the robust functionality needed to insert custom fields, tabs, and unique display options into these legacy core asset forms.

Case 2B.

Coincidentally, I stumbled upon a rather amusing option. I’m not sure if it’s of any use, but I’m sharing it anyway.

You can create additional fields on the Genericity-created dropdowns! Check it out in the screenshot below.

How cool is that?

In conclusion, GLPI 11’s Genericity feature and the Fields plugin are not replacements for each other; rather, they serve as complementary tools:

Use Case	Recommended Tool	Plugin Needed?
New, Custom Asset Creation	GLPI 11 Genericity Feature	NO
Adding Fields to Existing Core Assets (Computer, Contract, User, etc.)	Additional Fields Plugin	YES

By understanding this difference, you can leverage the new native capabilities of GLPI 11 for modern asset management while maintaining the flexibility of the Additional Fields plugin for your existing infrastructure.
