I have recently been working on a Joomla website and wanted to do the simple task of displaying my articles in a specific category on a page on under each other, just like a standard blog view.
I chose to use the ‘Category Blog’ menu item which worked perfectly until I wanted to display subcategories too. Any article I put in a subcategory no longer displayed on the page.
After lots of search the net I found the answer. The articles were actually being shown but the top level category articles were shown then each of the subcategories. So my article in the subcategory was moved to the end of the list, and due to pagination I didn’t see it on the first page.
To fix this, in the menu item settings, on the right hand side, select the option ‘Blog Layout Options’ and change ‘Category Order’ to ‘No Order’. This will make sure that the categories aren’t ordered in anyway so all articles that come under the parent category will be displayed in the order you specify.
