Using insertTag with renderUI fails
0
I have the following code to insert a tab which works:
library(shiny)
ui <- fluidPage(
navbarPage("My Page",
tabPanel("a", p("page a")),
tabPanel("b", p("page b")),
id='my_page')
)
server <- function(input, output, session){
v = reactiveVal(2)
observeEvent(v(),{
if(v() > 1){
cat("I did observe v with value", v(), "n")
insertTab(inputId="my_page",
tab=tabPanel("c", p("page c")),
target="a", position="after")
}
})
}
shinyApp(ui, server)
But a small modification on this, using renderUI & tagList shown below fails to insert the tab.
library(shiny)
ui <- fluidPage(
uiOutput("page")
)
server <- function(input, output, session){
output$page <- renderUI(tagList(navbarPage("My Page",
tabPanel("a", p("page a")),
tabPanel("b", p("page b")),
id='my_page')))
v = reactiveVal(2)
observeEvent(v(),{
if(v() > 1){
cat("I did observe v with value", v(), "n")
insertTab(inputId="my_page",
tab=tabPanel("c", p("page c")),
target="a", position="after")
}
})
}
shinyApp(ui, server)
What could be the reason? Please advise. Thanks.
