single select with `treeInput`

[lgnbhl]

When using shinyWidgets::treeInput(), is it possible in some way to have single selection (allowing users to select only a unique category of the tree)?

Thanks a lot for this amazing package!

Hello, unfortunately no it's not possible. I have plan to integrate another tree widget with more options and single select, but it's not ready yet.

Hello Victor,

Thank you for your quick answer, and sorry for my late reply.

I have published a new R package (still experimental) which allows to switch between single and multiple selections with an multiSelect argument. The muiTreeView package is a wrapper of the MUI X Tree View React components.

Here an example of this functionality:

# remotes::install_github("lgnbhl/muiTreeView")
library(muiTreeView)

df <- data.frame(
  pkg = c("muiTreeView", "muiTreeView", "muiTreeView"),
  functions = c("SimpleTreeView", "RichTreeView", "RichTreeView"),
  args = c("items", "items", "onItemSelectionToggle")
)

treeItems <- muiTreeView::asMuiTree(df)

RichTreeView(
  items = treeItems,
  checkboxSelection = TRUE,
  multiSelect = TRUE # FALSE for single select
)

RichTreeView(
  items = treeItems,
  checkboxSelection = TRUE,
  multiSelect = TRUE # FALSE for single select
)

As you can see, I have implemented a customized version of your shinyWidgets::cree_tree(), thanks a lot for making it (I mentioned your work in my docs ;)).

The MUI Tree View React components allows also to easily style the widget with CSS and icons, as I show in the documentation of the package here: https://felixluginbuhl.com/muiTreeView/

Feel free to let me know what you think of my brand new R package ;).

Best,
Félix
