问题
In the given R shiny script below, I am trying to use a conditional panel with Picker Input shiny widget. There are three options in pickerInput, upon selection of "times" option, I wish to create new pickerInputs using a conditional panel, the following is possible using selectInput, but I need the same for Picker Input. Thanks and please help.
library(shiny)
library(shinydashboard)
ui <- dashboardPage(
dashboardHeader(title = "Picket",titleWidth = 290),
dashboardSidebar(width = 0),
dashboardBody(
tabsetPanel(type = "tab",
tabPanel("Overview", value = 1,
box(
column(1,
dropdown(
pickerInput(inputId = "resources",
label = "",
choices = c("cases",
"activities",
"times"),
choicesOpt = list(icon = c("fa fa-bars",
"fa fa-bars",
"fa fa-safari")),
options = list(`icon-base` = "")),
circle = FALSE, status = "primary", icon = icon("list", lib = "glyphicon"), width = "300px"
),
conditionalPanel(
condition = "input.Position == 'times' ",
dropdown(
pickerInput(inputId = "Id072",
label = "Select/deselect all options",
choices = c("A","Check-out", "b","c","d","e","f")
)))))),
id= "tabselected"
)
))
server <- function(input, output) {
}
shinyApp(ui, server)
回答1:
Shouldnt this condition = "input.Position == 'times' ", be condition = "input.resources == 'times' ",?
