Views Bulk Operations (VBO) is a Drupal module that allows users to perform bulk operations on multiple content items from within a view. It provides a way to quickly and easily perform actions such as publishing, unpublishing, deleting, or updating content. VBO is especially useful for administrators who need to manage large amounts of content quickly and efficiently.

VBO works by adding a new field to a view, which allows users to select multiple content items and then perform an action on them. The field can be configured to display checkboxes, radio buttons, or a drop-down menu. Once the desired content items have been selected, the user can then choose an action to perform on them. The available actions are determined by the administrator and can include publishing, unpublishing, deleting, or updating content.

VBO is a powerful tool for managing content in Drupal. It allows administrators to quickly and easily perform bulk operations on multiple content items, saving time and effort. It is also a great way to ensure that content is up-to-date and accurate, as it allows administrators to quickly and easily update multiple content items at once.
