Joomla 3.x Search Engine Friendly URL for Articles

I've got a website using Joomla 3.x. The menu items are as follow:

• Home
• Category A (alias: cat-a)
• Category B (alias: cat-b)

where Category A and B are in Category List type.

Also I have set up two categories, Category A and Category B (same alias as menu items) and both contain a few articles which it looks like this:

• Category A (alias: cat-a)
• Article 1 (alias: art-1)
• Article 2 (alias: art-2)
• Category B (alias: cat-b)
• Article 3 (alias: art-3)
• Article 4 (alias: art-4)

At first, I expect when I visit Article 1, the URL would be something like: http://www.example.com/cat-a/art-1 and good news is it does happen.

However, with the same settings, it looks differently when visiting Article 3: http://www.example.com/art-3

So the question is, how can I make the URL of Article 3 looks like that of Article 1?

P.S. I didn't use any extension for SEF, just the one included in Joomla distribution.

• Hi Tony :) Welcome to Joomla SE. If my answer doesn't help you, please tell us what SEF extensions you are using on your site (if any). Also information or a picture of your menu structure would help. Thanks. – TryHarder Jun 13 '14 at 5:28
• thanks @moomoochoo. may be i didn't tell in the correct way. actually those articles are not a menu item. i tried to made it clear by editing the original question, see if it is easier to understand. :) – Tony Leung Jun 13 '14 at 6:37
• Finally find the answer. It's because there is another menu item that is linked to the same category list. So somehow it detect conflicts and didn't add the alias of category. – Tony Leung Jun 13 '14 at 8:02
• OK, glad you found it. You should write that as the answer for the question. – TryHarder Jun 13 '14 at 8:08

For a achieving something like this, you need to have the corresponding menu items of type Articles -> Category Blog for every category.
The menu item alias will be responsible for the the URL part of the category, while the articles' URL part, will be fulfilled by the article's alias.
