Navigation elements like sidebars, menus, and lists are essential UI components. Learn how to extract these structures.
from askui import VisionAgent, ResponseSchemaBase
from typing import List
class SidebarItem(ResponseSchemaBase):
name: str
children: List["SidebarItem"]
class Sidebar(ResponseSchemaBase):
sidebar: List["SidebarItem"]
with VisionAgent() as agent:
agent.tools.webbrowser.open_new("https://docs.askui.com")
agent.wait(3) # Wait for page to load
result = agent.get("Can you extract me the sidebar?", response_schema=Sidebar)
print(result.model_dump_json(indent=2))
Best Practices
- Handle Empty Lists: Always check if lists are empty
items = agent.get("What are the menu items?", response_schema=List[str])
if not items:
print("No menu items found")
else:
print(f"Found {len(items)} menu items")
