# Tab Information

> Extract tab data and manage tab-based navigation

Tabs are common UI patterns for organizing content. Learn how to extract tab information, identify active tabs, and navigate between them.

## Basic Tab Extraction

```python theme={null}
from askui import VisionAgent, ResponseSchemaBase
from typing import List

class Tab(ResponseSchemaBase):
    name: List[str]
    active: bool

class TabBar(ResponseSchemaBase):
    tabs: List[Tab]

with VisionAgent() as agent:
    agent.tools.webbrowser.open_new("http://docs.askui.com")
    agent.wait(3)  # Wait for page to load

    result = agent.get("Can you extract me the tabs?", response_schema=TabBar)
    print(result.model_dump_json(indent=2))
```

## Best Practices

1. **Handle Dynamic Tabs**: Some applications add/remove tabs dynamically
   ```python theme={null}
   initial_tabs = agent.get("How many tabs are there?", response_schema=int)

   # After some action
   agent.click("Add new tab")

   new_tab_count = agent.get("How many tabs are there?", response_schema=int)
   assert new_tab_count == initial_tabs + 1
   ```

2. **Tab Loading States**: Wait for tab content to load
   ```python theme={null}
   agent.click("Click on Data tab")

   # Wait for content
   content_loaded = False
   for _ in range(10):  # Timeout after 10 attempts
       content_loaded = agent.get(
           "Is the tab content fully loaded?", 
           response_schema=bool
       )
       if content_loaded:
           break
       agent.wait(1)
   ```

3. **Keyboard Navigation**: Some tab interfaces support keyboard navigation
   ```python theme={null}
   # Use keyboard shortcuts for tab navigation
   agent.key("Ctrl+Tab")  # Next tab
   agent.key("Ctrl+Shift+Tab")  # Previous tab
   ```
