Styled Paper - Copy this React, Mui Component to your project

Create a nested checkbox list, where each main item can expand to reveal a set of sub items with checkboxes. The main items should be clearly distinguishable, with checkboxes for selecting primary options, and the nested sub items should be indented underneath the corresponding main item. Each sub item should also have a checkbox for selection. The design should allow for smooth interaction, enabling users to toggle the visibility of the nested options with a clean, organized layout. Use clear hierarchy, with distinct spacing and alignment, to ensure the list remains easy to navigate and visually appealing. Make sure the design is responsive, adapting seamlessly across all devices and screen sizes.
