将元素添加到组元素的顶部 [英] Adding an element to top of a group element
问题描述
在使用我的群组加入资料后,我想要将输入
选项中的元素加入群组( g
-element)在顶部/最高。默认是附加到底部。
After joning data with my group I would like the elements in the enter
selection to be added to a group (g
-element) on top/highest up. Default is to append to the bottom.
这是因为我想让对象在所有现成的可见对象下方显示。
The reason for this is that I want the object to visually appear below the all ready visible objects.
我知道我可以订购和排序,但我认为可能有一个更容易/更好的方法来做到这一点。我做了几个手动的事情只是为了后来发现Oooh,他们包括一个聪明的方式来做,EASILY。
I know I can order and sort but I thought there might be an easier/better way to do this. I have done several manual things only to later find out "Oooh, they included a smart way to do that, EASILY."
