PHP 7.1 & Mysql 5.7

" the last test version of Joomla" by latest version do you mean Joomla 3.7 rc2 or what version of your Joomla is the "latest" version with hidden menu option?

Version 3.7 rc2

@ArjanRoosemalen Can't confirm: Set an Menu Single Contact in Tab Link Type > Display in Menus on No. Menu isn't shown in Frontend, but Link (click on "Author" in Article on Frontend) works.

There is no button for me to not show the menu item on the frontend. See illustration.
For the update to 3.7 rc1 or 2 it all worked well.

@ArjanRoosemalen set Menu-item-type you need. Click Tab Link Type (Screenshot shows Linktype).

I have now done but the problem remains that the category and product id still get shown once in the address bar of the browser when you click on the title of the article or the "Read more" link.

Test on fresh Install 3.7-rc2 + Sample Sites:

• Blog-Menu "index.php/en/park-blog"
• Article-Url: "index.php/en/park-blog/17-first-blog-post"

Same Urls if set Menu on "Display in Menu: No".

As far as i understand you got no Article-ID in this Setting?

Maybe images make clear what I mean.

Test on fresh Install 3.7-rc2 + Sample Sites. Made menu-item single article for Happy Orange Orchard article and set it to "hide" and inserted readmore in article.
Clicking on readmore or on article title leads to wrong url.
Hidden menu-item works:

Did some more tests:
Link to hidden menu-item type category-blog in article seems to be ok. Link to single article (also hidden menu-item) appends article id.

@Pinkeltje so you confirm the Issue?

Yes I do confirm the issue.

thanks @Pinkeltje set Status at issue Tracker on "Confirmed".

Hello,
Hey
I use latest Joomla version, 3.7.0-dev.

And using the read more button in arikel
the same problem

I tried to reproduce the issue but get 404 on demo-site when setting "Use URL Rewriting" to "Yes":

on https://demo.joomla.org/ click "Launch Test Drive"
click Content-New Article, create article (myarticle) with read-on, create category on the fly, save&close.
click menu-item, create new menu-item type category-block, select created category, select MAIN menu, save&close.
click Menues-Manage-Add New Menu, create new menu, save&close.
click menu-item, create new menu-item type single Article, select created Article (myarticle), select created menu (hidden, no module), save&close.

test frontend, clicking read-on: no item-id in url: http://j2950aac101.demojoomla.com/index.php/myarticle
=> ok, cannot confirm issue

click Configuration-Global, set Use URL Rewriting to "Yes", save&close
test frontend, clicking new menu-item in main-menu (type category-block): 404
=> different issue, cannot further investigate this issue (Test Drive: J3.7.0)

@ArjanRoosemalen have you test "Display in Menu" in Menu-Tab "Link-Type"?

Closed as a site setup issue and not a core bug
