👉 Collapsible is a term that refers to an object or system that can be extended or collapsed, either vertically or horizontally. It's often used in the context of furniture and construction where it's designed to make space more usable. In simple terms, "collapsable" means that the object or system can be broken down into smaller elements, allowing for easier manipulation and organization. For example, a bookshelf might have multiple shelves that can be collapsed to create more room for additional books or other items
