This device is a device that displays multiple data items in a tree structure. This device contains: a display means (200) that displays the tree structure; a first recognition means (202) that responds to a selection of a first node, and as a first node group, recognizes all nodes connected from the first node in the higher-level direction and the lower-level direction; a second recognition means (204) that responds to a selection of a second node, and as a second node group, recognizes all nodes that connect from the second node in the higher-level direction and the lower-level direction; a movement means (206) that receives an operation moving the second node to the first node, and moves the second node group toward the first node; an identification means (208) that in accordance with a preset rule, identifies a node for which display should be omitted; and an instruction means (210) that issues an instruction for the display of the identified node to be omitted, and for the first node group and the second node group to be displayed nearby one another.</p> |
