Show content (one section or text) of one page only to logged in users

I want to show some content (maybe one section or some text) of a page only to logged in users. How do I make it possible?

I am thinking of something like:
modx.user.id:isloggedin= `HTML Code`

or maybe any solution with a chunk where I put the HTML Code in. Help?

Okay, some minutes later I finally found a solution for short texts.
Hope it's still a good way:



But this only works for short texts/content. What if I want to put several lines of HTML to the "else"? What if I want to make a whole section of content visible to the logged in user? What is the solution for this case?

The above solution will also work well for multi html lines or chunks. You could alternatively create a snippet that will show chunk A or chunk B depending on if the user is logged in or not.

Ah, true. I just need to put in the chunk placeholder into the else statement? Sounds quite logical. But multiple html lines (with sections, divs, classes, etc) are not shown with syntax highlights (with extra: ace), when placed into the else statement. So chunks would be the better choice, I guess.

You might look at the Personalize snippet, which shows different chunks to logged-in and not-logged-in users.
