Don't add a drag bar
An action bar appears when items in a list or grid view are selected, and it remains in place until items are deselected or a user navigates away. Action bars can not be moved or dragged.
Allow scrolling to view underlying content
Action bars appear on top of content. Allow space for a user to still be able to view the content underneath, especially if they're taking actions on a table or a list of items and need to be able to scroll.
Don’t use quick actions
Instead of quick actions, use an action bar for both single and bulk selection patterns. An action bar is useful for when a user needs to perform actions on either a single or multiple items at the same time. It can be used on either a grid view or a table view.
Don’t use quick actions — a deprecated component — because it presents conflicting nested actions (for example, a whole asset card could open a detailed view). This makes targeting specific actions very difficult, especially on smaller screens or with the keyboard.
