changing menu item from custom link to page

Is it possible to change it into page

Can you clarify what you mean by this?

I mean that when i make a new page which i then add to a menu it is set as a page. I installed a theme and installed demo content to help me out. Now I have a whole menu and sub menu where some menu items link to a page but not all. Some menu items link to a custom link or even an external link, I wonder if i can manually change that ‘back’ into a page

Have you reviewed custom menus?

Yes, it didn’t have an answer to my question.
can i add a screenshot here?

Yes, it didn’t have an answer to my question.

Why? What part are you having a problem with?

Okay, say I have a main menu with 2 pages, Home, Contact,. They both link to a page with content. Say I have a Home, Contact, Shop and the shop is not a page but an external url, a link to a completely different website.

Now I want to change this Shop into a page with say my blogcontent. I don’t want it to link to a different website. Is that possible or can I only delete this Shop and create a new page and add it to the menu?

I don’t think I can describe it better than that without a screenshot…:-)

Now I want to change this Shop into a page with say my blogcontent.

With a custom menu, you can delete the existing menu item and replace it with one of your own choosing.

That’s what I guessed. Can I also hide it as I asked in my second question?

Can you hide what? A single menu item or a whole menu?

A single menu item.
