WASHINGTON—Top secret and other classified documents at Mar-a-Lago were kept in boxes that also held newspaper and magazine clippings, clothing and gifts, according to a more detailed list, made public Friday, of items FBI agents seized in their search of former President Donald Trump’s home last month.

Agents took around 33 boxes, containing more than 100 classified documents, prosecutors have said. Seven of the boxes or containers were located in Mr. Trump’s office and the rest in a storage room at the private club, according to the inventory.
