我想要实现的用户可以灵活地禁用/启用二级过滤器 id2('Resource') 和 id3('Case')：

  1. id2('Resource')并id3('Case')启用：程序根据 id1、id2 和 id3 过滤器显示相关结果
  2. id2('Resource')并id3('Case')禁用：程序仅显示级别 1 id1('ThrouputTime') 过滤结果。

我在下面实现（pheusdo）代码，程序将在SAMETIME根据这3个过滤器获取结果，但无法实现上述第二种情况。有什么建议吗？ 

ui <- dashboardPage(
    dashboardBody(
        tabItems(
                tabItem(tabName = "dashboard",
            fluidRow(
                        box(
                            title = "ThrouputTime",
                            width = 3,
                            sliderInput(inputId="id1", label="ThrouputTime", ...)
                           )    
                ),      
            fluidRow(
                        box(
                            title = "Resource",
                            width = 3,
                            selectInput(inputId="id2", label="resource", ...)
                           ),
                box(
                            title = "Case",
                            width = 3,
                            selectInput(inputId="id3", label="case", ...)
                           )
                )
            )
              )
           )



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

  observe({
    output$process <- renderProcessanimater(expr = {

      filtered_event <- newevent %>%
        filter_throughput_time(interval = c(input$throughput[1], input$throughput[2])) %>%
        filter_resource(input$id2)  %>%                 
        filter_case(input$id3, reverse = F)                   

        #.... generate a workflow graph based on 'filtered_event' from above    
    })
  })
}

graph <- shinyApp(ui, server)
runApp(graph, host = "0.0.0.0", port = 5050)
