Is there a way in which the menu can automatically collapse back once a country is selected?

Hi @pvictor ,

Thank you so much for this package.

Is there a way in which the menu can automatically collapse back once a country is selected?

`
library(shiny)
library(shinytreeview)

data("cities")

ui <- fluidPage(
tags$h3("treeviewInput cities example"),
treeviewInput(
inputId = "tree",
label = "Choose a city:",
choices = make_tree(
cities, c("continent", "country", "city")
),
multiple = FALSE,
prevent_unselect = TRUE,
width = "100%"
),
verbatimTextOutput(outputId = "result")
)

server <- function(input, output, session) {
output$result <- renderPrint({
input$tree
})
}

if (interactive())
shinyApp(ui, server)
`

Start from the treeviewInput entry point and the cities example shown in the issue. Trace how a single country selection is handled and determine how the menu's expanded state is controlled. Done means selecting a country automatically collapses the menu in the provided Shiny example.

Written by the indexing model from the issue text.
