I have a dataTableOutput in my main panel. Then I have an action button "Go". Once I click "Go" I want rHandsOutput to appear in the main panel but not beneath dataTableOutput. How can I remove dataTableOutput in the main panel and display rHandsOutput. In my current code both tables appearing together. Once I click "Go", the second table comes under the first table where I want to appear only second table (rHandsOutput) removing 1st table from the main panel.
Please help me!1
You can use a combination of insertUI
and removeUI
to make UI components dynamic. For example:
library(shiny)
ui <- fluidPage(
sidebarLayout(
sidebarPanel(
actionButton(inputId = "go", label = "Go")
),
mainPanel(
fluidRow(
tags$div(id = "firstOutput",
dataTableOutput("myDataTable"))
),
fluidRow(
tags$div(id = "placeholder") # the dynamic UI will be inserted relative to this placeholder
)
))
)
server <- function(input, output) {
output$myDataTable <- renderDataTable(iris)
observeEvent(input$go, {
removeUI("div:has(>#firstOutput)")
insertUI(
selector = "#placeholder",
where = "afterEnd", # inserts UI after the end of the placeholder element
ui = fluidRow(
actionButton(inputId = "newButton", label = "A new button")))
})
}
shinyApp(ui = ui, server = server)
You can use showElement()
and hideElement()
from shinyjs
:
observeEvent(input$go, {
shinyjs::hideElement(“firsttable”)
shinyjs::showElement(“rHandsOutput”)
})
Assuming the ID of the first table is “firsttable” and the ID of the second table is “rHandsOutput”, and the ID of the “Go” button is “go”.
Generate the ui dynamically.
Use uiOutput("someidentifier")
in the ui.r
and then fill it with your datatable with the following in server.r
output$someidentifier <-
renderUI({
dataTableOutput("datatableidentifier")
})
output$datatableidentifier <- renderDataTable(iris)
uiOutput
takes the place (in ui.r
) of whatever ui element you want to add dynamically. The necessary code for that ui then moves to renderUI
in server.r
.
