You can add tags to your path parameter, for example.

If you have something like this, using tags is extremely helpful.

@app.delete("/items", tags=["Delete Methods"])
@app.put("/items", tags=["Put Methods"])
@app.post("/items", tags=["Post Methods"])
@app.get("/items", tags=["Get Methods"])
async def handle_items():
    return


@app.get("/something", tags=["Get Methods"])
async def something():
    return

You will get this, also if you want to add description and you don't want to keep repating yourself (For example adding same description in all parameters)

You can use openapi_tags (I prefer this)

from fastapi import FastAPI

tags_metadata = [
    {"name": "Get Methods", "description": "One other way around"},
    {"name": "Post Methods", "description": "Keep doing this"},
    {"name": "Delete Methods", "description": "KILL 'EM ALL"},
    {"name": "Put Methods", "description": "Boring"},
]

app = FastAPI(openapi_tags=tags_metadata)


@app.delete("/items", tags=["Delete Methods"])
@app.put("/items", tags=["Put Methods"])
@app.post("/items", tags=["Post Methods"])
@app.get("/items", tags=["Get Methods"])
async def handle_items():
    return

This will give the same look without repetition
