Menu

class praw.models.Menu(reddit, _data)

   Class to represent the top menu widget of a subreddit.

   Menus can generally be found as the first item in a subreddit's top
   bar.

      topbar = reddit.subreddit('redditdev').widgets.topbar
      if len(topbar) > 0:
          probably_menu = topbar[0]
          assert isinstance(probably_menu, praw.models.Menu)
          for item in probably_menu:
              if isinstance(item, praw.models.Submenu):
                  print(item.text)
                  for child in item:
                      print('\t', child.text, child.url)
              else:  # MenuLink
                  print(item.text, item.url)

   Create one (requires proper moderator permissions):

      widgets = reddit.subreddit('redditdev').widgets
      menu_contents = [
          {'text': 'My homepage', 'url': 'https://example.com'},
          {'text': 'Python packages',
           'children': [
               {'text': 'PRAW', 'url': 'https://praw.readthedocs.io/'},
               {'text': 'requests', 'url': 'http://python-requests.org'}
           ]},
          {'text': 'Reddit homepage', 'url': 'https://reddit.com'}
      ]
      menu = widgets.mod.add_menu(menu_contents)

   For more information on creation, see "add_menu()".

   Update one (requires proper moderator permissions):

      menu_items = list(menu)
      menu_items.reverse()
      menu = menu.mod.update(data=menu_items)

   Delete one (requires proper moderator permissions):

      menu.mod.delete()

   **Typical Attributes**

   This table describes attributes that typically belong to objects of
   this class. Since attributes are dynamically provided (see
   Determine Available Attributes of an Object), there is not a
   guarantee that these attributes will always be present, nor is this
   list comprehensive in any way.

   +-------------------------+-----------------------------------------------------+
   | Attribute               | Description                                         |
   +=========================+=====================================================+
   | "data"                  | A list of the "MenuLink"s and "Submenu"s in this    |
   |                         | widget. Can be iterated over by iterating over the  |
   |                         | "Menu" (e.g. "for item in menu").                   |
   +-------------------------+-----------------------------------------------------+
   | "id"                    | The widget ID.                                      |
   +-------------------------+-----------------------------------------------------+

   mod
