推荐答案
检查这是否或多或少你想要的（你需要提供一个小图标文件被拖动 - 在源文件中更新文件名）。只要提到带有图标拖动的货架，就可以放置在地图之外的任何位置。
Check if this is more or less what you wanted ( you will need to provide a small icon file to be dragged - update file name acorrdingly in the source). Just to mention the shelf with icons to drag can be placed anywhere also outside of the map.
