A wrapper of the JavaScript library jsTree. This package is similar to shinyTree but it allows more options. It also provides a Shiny gadget allowing to manipulate one or more folders.

Install from CRAN:

install.packages("jsTreeR")

Or install the latest development version (on GitHub):

remotes::install_github("stla/jsTreeR")

Please check the Shiny examples (see ?jstreeExamples).

The 'tree navigator' has not all the features of the 'folder gadget', it only allows to navigate in the server side file system and to select some files. But the 'folder gadget' loads all the structure of the root folder(s), while the 'tree navigator' loads the contents of a clicked folder only when this one is clicked by the user. And as a Shiny module, it is possible to build around it a more elaborated Shiny app.
