In order to create and publish a Content Item, please go to the Content menu and select All Content Items.
All the items that have been included in Joomla article list up to date will be displayed. You will be able to manage existing ones or create new by clicking the respective icon:
The process of creating a new article is very similar to the one through which the Sections and the Categories are being created. This time around you will need to select both the parenting Section and Category, in order to create an article.
In this case instead of a description you will be able to enter a short introductory text. It will appear in the main Section / Category page ending with a link to continue reading further the rest of the article. This short introduction may also show on your frontpage if you have published it there. There are other options, such as: where the item will appear in menus, to add pictures, manage the authorship and publishing date, etc.
When done, please click the [Save] icon to complete the creation process. You will be able to see the new item listed in the Content Items Manager.
The last thing to do in order to have the item online is to publish it - just click on the red X and that will publish the article.
You can also change the order in which the articles appear through clicking the up- and down-pointed triangles respectively. That can be also done through changing the number in the Order box that you see on the same line and then pressing the Enter key on your keyboard. The smaller the number in the box, the higher the article appears. The changes will be automatically applied and you will see the changes when the screen refreshes.
