jsTreeR affects other htmlwidgets' styling

[datatenk]

After switching from shinyTree to jsTreeR, all other htmlwidgets appear to have their styling set to those of jsTree when they are rendered through renderUI.

As exemplified below, a shinyWidgets::radioGroupButtons element is used:

1. when using shinyTree, the following rendering is obtained (desirable):
   

2. after switching to jsTreeR, the following rendering is obtained (undesirable):
   

Below is a reprex, firstly using shinyTree, where the renderings are good in both "shinyTree" and "shinyTree uiOutput" tabs:

library(shiny)
library(bslib)
library(shinyWidgets)
library(shinyTree)
library(jsTreeR)

# using shinyTree
nodes_shinyTree<-list(foo=list(bar=list()))

shinyTree_ui<-card(
  shinyTree('shinyTree_tree_ui'),
  radioGroupButtons('rgb1',choices=c('A','B'),size='sm'))

ui_shinyTree<-page_navbar(
  title='shinyTree',
  
  nav_panel(
    title='shinyTree',
    card(
      shinyTree('shinyTree_tree'),
      radioGroupButtons('rgb',choices=c('A','B'),size='sm')
    )
  ),

  nav_panel(
    title='shinyTree uiOutput',
    uiOutput('shinyTree_ui')
  )
  
)

server_shinyTree<-function(input,output,session){
  output$shinyTree_tree<-renderTree(nodes_shinyTree)
  
  output$shinyTree_tree_ui<-renderTree(nodes_shinyTree)
  output$shinyTree_ui<-renderUI(shinyTree_ui)
  
  
}

shinyApp(ui_shinyTree,server_shinyTree)

Same example, now using jsTreeR instead of shinyTree; notice the problem in the "jsTreeR uiOutput" tab:

library(shiny)
library(bslib)
library(shinyWidgets)
library(shinyTree)
library(jsTreeR)


# using jsTreeR
nodes_jsTreeR<-list(list(text='foo',children=list(list(text='bar'))))

jsTreeR_ui<-card(
    jstreeOutput('jstree_tree_ui'),
    radioGroupButtons('rgb1',choices=c('A','B'),size='sm'))


ui_jsTreeR<-page_navbar(
  title='jsTreeR',
  
  nav_panel(
    title='jsTreeR',
    card(
      jstreeOutput('jstree_tree'),
      radioGroupButtons('rgb',choices=c('A','B'),size='sm')
    )
  ),

  nav_panel(
    title='jsTreeR uiOutput',
    uiOutput('jsTreeR_ui')
  )
)

server_jsTreeR<-function(input,output,session){
  output$jstree_tree<-renderJstree(jstree(nodes_jsTreeR))
  
  output$jsTreeR_ui<-renderUI(jsTreeR_ui)
  output$jstree_tree_ui<-renderJstree(jstree(nodes_jsTreeR))
  
}

shinyApp(ui_jsTreeR,server_jsTreeR)

Hello,

Thanks for the report. That is very strange. This is not due to the jsTreeR contained in the renderUI: if you remove it, you get the same strange behavior. I inspected the HTML code and I observed that the code for the button groups is different. In the first tab, there are only input type="radio" elements, while in the second tab, there are some button elements in addition. I have really no idea where are they from.

If by "removing jsTreeR" could restore the radioGroupButtons to its original rendering, that has been tried and shown in my Reprex in which I used renderUI with shinyTree to achieve the correct rendering of radioGroupButton. However, it highlights the points that once renderUI is paired with jsTree, the radioGroupButton rendering breaks. There are actually 2 separately formed shinyApps in my reprex, one for each wrapper. The only difference between the 2 apps in my reprex is which jsTree wrapper is being used, shinyTree vs jsTreeR.

Here https://github.com/stla/jsTreeR/blob/master/R/jstree.R#L458 you load Bootstrap 3 (Shiny default) as dependency, but bslib::page_navbar() by default load Bootstrap 5.
A priori, when the renderUI is run, the Bootstrap theme of the server is updated to Bootstrap 3, whereas the HTML page uses Bootstrap 5 and radioGroupButton() generates an incorrect HTML markup (the one for BS 3).

Here an example where you can see the Bootstrap version being updated from 5 to NULL (the default, 3).
