To order articles on category pages
By default Joomla displays articles on the category pages in the order in which you publish them.
- On the Content menu, click Content by Section and then click the Section whose articles you want to order and then click <section name> items.
- In the Content Items Manager screen, in the Order column, type the order number for each article and then click the Save icon
next to Order to save the new article order.
Note: You can also reorder articles by click the Reorder arrow in the article's row.
