r - sortable包中bucketlist的选择问题

Question

我的数据中有 3 个区，分别是 A、B 和 C。我想从当前区的分区中建立一个新区。例如，我通过 selectInput 选择了 3 个区中的 2 个。然后，我想使用 bucket_list 来选择分区。遗愿清单应显示所选地区的分区。我不想在遗愿清单上看到第三区的分区。我只想查看通过 selectInput 选择的内容。我无法做到这一点。之后，我想根据我在桶列表中选择的内容使用 DT 包创建一些表。我的代码如下。如果你能帮忙，我会很高兴。

这是代码：

library(semantic.dashboard)
library(ggplot2)

   dashboardBody(
       tabItems(

           tabItem(

                                              selected = 0,
                                              multiple= TRUE),

                   ),
                   if(interactive()) {
                       bucket_list(
                           header = c("NEW DISTRICT ESTABLISHMENT"),
                           add_rank_list(
                               text = "PLEASE SELECT SUBDISTRICT HERE!",

                           add_rank_list(
                               text = "select the subdistricts of the new district"
                           ),
                           add_rank_list(
                               text = "select the subdistrict of the current district"
                           ),
                           add_rank_list(
                               text = "select the subdistrict of the current district 2"
                           )    
                       )
                   }
                   
               ),
               
               )
           )
       ), 
       theme = "cerulean"
   )


server <- shinyServer(function(input, output, session) {
   
   observe({ print(input$select) 
       #output$x <- data$SUBDISTRICT[data$DISTRICT == input$select]  
       #output$x <- data %>% filter(DISTRICT == input$select) %>% select(SUBDISTRICT) 
       #updateSelectInput(session,"SUBDISTRICT","Select a SUBDISTRICT Category",choices = unique(x))
   })
   
   output$value <- renderText({paste(input$select)
       
       
       
   })
   
   output$value1 <- renderText({ input$caption })
   
   

   })

shinyApp(ui, server)

另外，当我在这些代码上删除 # 时：

observe({ print(input$select) 
       #output$x <- data$SUBDISTRICT[data$DISTRICT == input$select]  
       #output$x <- data %>% filter(DISTRICT == input$select) %>% select(SUBDISTRICT) 
       #updateSelectInput(session,"SUBDISTRICT","Select a SUBDISTRICT Category",choices = unique(x))

闪亮的关闭本身。
