By wordpress theme default, if I have menu category in sidebar,
when I click on post's title I see the post e not more the sidebar
(I have the single.php file).
If I insert insert in the single.php file, the sidebar, then I see
sidebar and post.
but the menu in the sidebar lose all the settings.
Example if I use an highlight menu, when I click on category I have
highlight the category, but how I clickl in the article lose that.
Others problem: if I use a plugin (example Fold category List)
that have the tree submenu, If I am in a submenu and click
in the article I lose the tree and the menu return at the initial
position (first I go in the submenu).
