shinyTree

The shinyTree package enables Shiny application developers to use the jsTree library in their applications.

Installation

You can install the latest development version of the code using the devtools R package.

```

Install devtools, if you haven't already.

install.packages("devtools")

library(devtools) install_github("shinyTree/shinyTree") ```

Getting Started

01-simple (Live Demo)

library(shiny) runApp(system.file("examples/01-simple", package = "shinyTree"))

A simple example to demonstrate the usage of the shinyTree package.

02-attributes (Live Demo)

library(shiny) runApp(system.file("examples/02-attributes", package = "shinyTree"))

Manage properties of your tree by adding attributes to your list when rendering.

03-checkbox (Live Demo)

library(shiny) runApp(system.file("examples/03-checkbox", package = "shinyTree"))

Use checkboxes to allow users to more easily manage which nodes are selected.

04-selected (Live Demo)

library(shiny) runApp(system.file("examples/04-selected", package = "shinyTree"))

An example demonstrating how to set an input to the value of the currently selected node in the tree.

05-structure (Live Demo)

library(shiny) runApp(system.file("examples/05-structure", package = "shinyTree"))

Demonstrates the low-level usage of a shinyTree as an input in which all attributes describing the state of the tree can be read.

06-search (Live Demo)

library(shiny) runApp(system.file("examples/06-search", package = "shinyTree"))

An example showing the use of the search plugin to allow users to more easily navigate the nodes in your tree.

07-drag-and-drop (Live Demo)

library(shiny) runApp(system.file("examples/07-drag-and-drop", package = "shinyTree"))

An example demonstrating the use of the drag-and-drop feature which allows the user to reorder the nodes in the tree.

08-class (Live Demo)

library(shiny) runApp(system.file("examples/08-class", package = "shinyTree"))

An example demonstrating the use of the ability to style nodes using custom classes.

09-themes

library(shiny) runApp(system.file("examples/09-themes", package = "shinyTree"))

An example demonstrating the use of built-in tree themes.

10-node-ids

library(shiny) runApp(system.file("examples/10-node-ids", package = "shinyTree"))

An example demonstrating the ability to label and return node identifiers and classes.

11-tree-update

library(shiny) runApp(system.file("examples/11-tree-update", package = "shinyTree"))

An example demonstrating the ability to update a tree with a new tree model. This was broken in the original version as the tree was destroyed upon initialization.

12-types

library(shiny) runApp(system.file("examples/12-types", package = "shinyTree"))

An example demonstrating node types with custom icons.

13-icons

library(shiny) runApp(system.file("examples/13-icons", package = "shinyTree"))

An example demonstrating various ways to use icons on nodes.

14-files

library(shiny) runApp(system.file("examples/14-files", package = "shinyTree"))

Demonstrates how to create a file browser tree.

15-files

library(shiny) runApp(system.file("examples/15-data", package = "shinyTree"))

Demonstrates how to attach and retreive metadata from a node.

16-async

library(shiny) runApp(system.file("examples/16-async", package = "shinyTree"))

Demonstrates how to render a tree asynchronously.

17-contextmenu

library(shiny) runApp(system.file("examples/17-contextmenu", package = "shinyTree"))

Demonstrates how to enable the contextmenu.

18-modules

library(shiny) runApp(system.file("examples/18-modules/app.R", package="shinyTree")) runApp(system.file("examples/18-modules/app_types.R", package="shinyTree"))

Demonstrates how to use shinyTree with shiny modules.

19-data.tree

library(shiny) runApp(system.file("examples/19-data.tree", package = "shinyTree"))

Demonstrates how to pass a data.tree to shinyTree.

20-api

library(shiny) runApp(system.file("examples/20-api", package = "shinyTree"))

An example demonstrating how to extend the operations on the tree to the rest of the jsTree's core functionality.

21-options

library(shiny) runApp(system.file("examples/21-options/app_setState_refresh.R", package="shinyTree"))

Demonstrates how to fine-tune shinyTree's behaviour with options. Specifically: When internal jstree code calls set_state or refresh, a callback is made so that the shiny server is notified and observe and observeEvents for the tree are fired. This can be useful if the developer would like observe and observeEvents to run after using updateTree. (By default, updateTree does not run observe or observeEvent because it is assumed that the shiny application knows that the tree is being changed already.)

23-file-icons

library(shiny) library(shinyTree) runApp(system.file("examples/23-file-icons", package = "shinyTree"))

An example demonstrating how to create a file tree with individual icons.
