How works the suggested articles in the Midrub Docs theme
The Midrub Docs theme has a widget with suggested articles. The articles are provided based on the selected category or the article's categories. The suggested articles feature is not based on the Midrub's core and it's available only in the Midrub Docs theme.
How the sugested articles are displayed? First of all, the script will verify if suggested articles exists. If not exists, will return the last articles. But if the suggested articles exists, them will be displayed based on the selected category(selected category and all its parents). For articles will be selected only the first article's category and all's its parents.
In this way, the suggested categories feature will show useful content to the user and similar content for search engines.
