Wikipedia lists lasagna under what type of Italian baked pasta dish?

Wikipedia lists lasagna under the type of Italian baked pasta dish called pasta al forno.

The Italian phrase al forno means “from the oven” or “oven-baked.” In this classification, lasagna is not simply a pasta shape: it is also a finished baked dish assembled from wide pasta sheets, fillings, sauces, and often cheese before being cooked in the oven.

The most familiar preparation stacks layers of pasta with ingredients such as ragù, béchamel, ricotta, mozzarella, vegetables, or other meats and dairy products. Regional recipes differ. Lasagne alla bolognese, from Emilia-Romagna, is traditionally built with ragù, béchamel, and Parmesan, while the Neapolitan version is richer and may include sausage, meatballs, eggs, ricotta, and mozzarella.

Pasta al forno is broader than lasagna. It can describe other pasta dishes baked with sauces, cheese, or fillings, so the phrase identifies a cooking style or dish category rather than one exclusive recipe. The related expressions lasagne al forno and lasagna al forno therefore emphasize the baked preparation, not a separate pasta species.
