如何在shiny中添加多个条件面板

library(shiny)

ui <- fluidPage(
  titlePanel("多条件面板示例"),
  sidebarLayout(
    sidebarPanel(
      conditionalPanel(
        condition = "input.condition1 == 'option1'",
        textInput("input1", "条件1输入框", value = "")
      ),
      conditionalPanel(
        condition = "input.condition2 == 'option2'",
        selectInput("input2", "条件2下拉菜单", choices = c("选项1", "选项2"))
      )
    ),
    mainPanel(
      conditionalPanel(
        condition = "input.condition1 == 'option1'",
        textOutput("output1")
      ),
      conditionalPanel(
        condition = "input.condition2 == 'option2'",
        plotOutput("output2")
      )
    )
  )
)

server <- function(input, output) {
  output$output1 <- renderText({
    input$input1
  })
  
  output$output2 <- renderPlot({
    plot(1:10, 1:10)
  })
}

shinyApp(ui, server)
