  +#### Customize Sorter
  +
  +In addition to the above implementation, we also added a more powerful `sidebarSorter` option to the theme options. You can pass one or a series of built-in sorter names, or you can pass a soter function you need to sort sidebar items at the same level.
  +
  +Available keywords are:
  +
  +- `readme`: `README.md` or `readme.md` first
  +- `order`: possitive order first with its value ascendingly, negative order last with its value descendingly
  +- `date`: sort by date ascendingly
  +- `date-desc`: sort by date descendingly
  +- `title`: alphabetically sort by title
  +- `title-number`: alphabetically sort according to title and ascendingly sort same titles with different number label
  +- `title-number-desc`: alphabetically sort according to title and descendingly sort same titles with different number label
  +- `filename`: alphabetically sort by filename
  +- `file-number`: alphabetically sort according to filename and ascendingly sort same filenames with different number label
  +- `file-number-desc`: alphabetically sort according to filename and descendingly sort same filenames with different number label
  +
  +Corresponding to the above advanced control, its default value is `["readme", "order", "title"]`
