I would like my submenus to stay centered with there top menus, but but won't stay like that, they always come back like this:
Furthur more, I used the widget horizontal menu, why is it that when I click on Contact, I can't put a link on it:
You required doing manual adjustments here, by selecting and dragging the handles of those particular submenus and menus.
I recommend, to adjust the menu, when your site is (nearly) ready. Because the submenu position unfortunately isn't relative to the parent menu, most changes within your menu will cause the submenus to snap back to their original position. (Not that unexpected by the way, because submenus can't know, which position is the desired one, if you, for example, change the width of the parent menu.
That is a little bit annoying, but do as I said: Adjust your submenus at the end of the creation process.
Your second question: You only can assign a link to a single menu entry in an automatic menu, if you set the page, which belongs to this menu, to "Include page without hyperlink" (= right click onto the page icon in plan mode -> menu options). Othwise the menu entry links to its corresponding page.
Thank you so much for your answer. It all works now!
