在0.22.0之前，二级标签是能合并在一起的，现在这个版本是bug呢，还是后续版本不再支持二级标签了呢

Title: 0.22.0 Secondary labels will not be merged and displayed.

确实二级标签都显示出来，感觉特别乱。 而且加载数量一多，比以前卡多了，不能另外做个管理界面嘛。。。

It is true that all secondary labels are displayed, which feels very messy. Moreover, when the number of loads increases, there will be more lags than before, so we cannot create another management interface. . .

After v0.22.0, it will be displayed horizontally instead of a tree. This could save more space and shows the amount of related memos.
