shinyTree

==========



The `shinyTree` package enables Shiny application developers to use the 

[jsTree](http://jstree.com) 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](https://trestletech.shinyapps.io/st-01-simple/))



```

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](https://trestletech.shinyapps.io/st-02-attributes/))



```

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](https://trestletech.shinyapps.io/st-03-checkbox/))



```

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](https://shinyTree.shinyapps.io/st-04-selected/))



```

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](https://trestletech.shinyapps.io/st-05-structure/))



```

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](https://trestletech.shinyapps.io/st-06-search/))



```

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](https://trestletech.shinyapps.io/st-07-drag-and-drop/))



```

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](https://trestletech.shinyapps.io/st-08-class/))



```

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](https://www.jstree.com/api/).



#### 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.
