DropDownTree

[msgoussi]

I am wondering if we can create a dropdown tree (TRISTATE) as it is shown in the website
https://demos.telerik.com/aspnet-ajax/dropdowntree/examples/functionality/checkboxes/defaultcs.aspx

since I do not have a enough space for shiny tree (which contains 100 elements).
ie World contains 6 continents, each continent has countries.

What if you combine shinyTree with shinyWidgets and include the tree in a dropdownButton?
Would that solve your issue?

Here's a small example:

library(shiny)
library(shinyTree)
library(shinyWidgets)

ui <- fluidPage(
  dropdownButton(circle = FALSE, label = "Show Tree",
    shinyTree("tree", stripes = TRUE, checkbox = TRUE)
  )
)

server <- function(input, output, session) {
  output$tree <- renderTree({
    list(
      root1 = "",
      root2 = list(
        SubListA = list(leaf1 = "", leaf2 = "", leaf3=""),
        SubListB = list(leafA = "", leafB = "")
      ),
      root3 = list(
        SubListA = list(leaf1 = "", leaf2 = "", leaf3=""),
        SubListB = list(leafA = "", leafB = "")
      )
    )
  })
}
shinyApp(ui, server)

Thanks for replying but I get an error when I run the code:
Error in shinyTree("tree", stripes = TRUE, checkbox = TRUE) :
unused argument (stripes = TRUE)

Just delete the stripes argument as it's not necessary for that example.
It uses the github version and not the current CRAN version.

@msgoussi Is you're problem solved with that example?
