Request: ability to create an accordion that is collapsed initially

[daattali]

It'd be nice to be able to do something like

library(shiny)
library(bsplus)

ui <- fluidPage(
  bs_accordion(id = "foo") %>%
    bs_append(title = "bar", content = "hello world", selected = FALSE)
)

server <- function(input, output, session) {
  
}

shinyApp(ui = ui, server = server)

so that the accordion will initialize in a collapsed state

I agree!

[daattali]

@ijlyttle this is the blocker for me :)

There are a couple ways to go about this - including your suggestion. I'll bug you about which you may think may be best.

[Patanouque]

You can remove the "in" class of the first element of the accordion by doing :

attrib_ = my_accordion$children[[1]]$children[[2]]$attribs
attrib_[which(attrib_ == "in")] = NULL
my_accordion$children[[1]]$children[[2]]$attribs = attrib_

Not very clean but it does the job

I am unsuccessfully trying to do the same thing using something like this:
bs_accordion(id = a_id) %>%
bs_set_aria("div", multiselectable = TRUE, expanded = FALSE) %>%
bs_append(title = paste(p_title, "Exposure", sep = " "),

Do you have any advice on how to best have the panels default as closed?

I just uploaded a function bs_multi_open in #112 that allows you to control which (if any) of the panels are initially open, as well as enabling/disabling multiple open panels.

Now available in PR #133 via the function bs_accordion_multi. The man page example demonstrates this (also shown in the comments to PR #113).
