You can create a collapsible navigation using HTML and CSS by using a combination of HTML for the structure and CSS for the styling and behavior. First, you would create a list of navigation items using HTML unordered list <ul> and list items <li>. Then, you would use CSS to style the navigation and set the initial display property of the list to none. Finally, you would use CSS to create a toggle effect when a user clicks on a button or icon, which would change the display property of the list to block, making it visible, and vice versa. This would create a collapsible navigation that can be expanded and collapsed as needed. **

It's also possible that the storage pool has reached its maximum capacity and cannot accommodate any additional drives.
