Question

我的目标是通过在同一insertUI中生成的框中的“ selectizeInput”呈现在insertUI中生成的输入。该问题涉及此问题（How to get the correct InputID while using InsertUI in Shiny）。基于@amrrs给出的答案和该问题的脚本，我想按如下所示扩展应用程序。

第一个部门的输出“总计”应显示“ Product11”和“ Product12”的输入总和。

第二部分的输出“总计”是“ Product21”和“ Product22”的输入之和。依此类推...

我尝试了很多，但没有任何效果。你们中的任何一个人不知道该怎么做吗？

所需的输出：

 #output$total <- renderText({out_rows()})



# Remove a division
observeEvent(input$remove, {

# Don't let the user remove the very first Row
if (num == 1) {

}


# Run the application 
shinyApp(ui = ui, server = server)
