In the menu settings, there is no column for "expanded," and there are issues with displaying submenus.

In general, I watched your lesson on Drupal, and you explain everything clearly, even though you're not an orator. However, I encountered a problem: when setting up the menu items, I didn't find the "Extended" column where I need to check the boxes. I downloaded Drupal from the official site - drupal.org version 7.20. I only installed the admin menu module and didn't change any templates. I would be very grateful if you could help me resolve this issue!!
