Drupal offers a variety of features, including user account registration and maintenance, RSS feeds, menu management, system administration, and page layout customization. It also provides an easy-to-use content creation and publishing system that allows users to create and manage different types of content such as blog posts, articles, and multimedia content.
Drupal’s modular architecture allows developers to add new functionality and features to the platform easily. This flexibility has helped Drupal become one of the most widely used content management systems in the world, powering millions of websites across a wide range of industries and sectors.
