I have a simplified shiny dashboard (see the code below). I want to fix the sidebar and the main header. So, with the help of other posts here, I write a CSS file to address the problem.
.sidebar {
color: #FFF;
position: fixed;
width: 220px;
white-space: nowrap;
overflow: visible;
}
.main-header {
position: fixed;
width:100%;
}
It almost works... The sidebar and the main header are fixed but there is a problem with the main header who hide the header of the first box. I guess that there is a few keyword in CSS to solve the problem but I didn't find them (newbie in CSS...).
The Shiny dashboard code is the following.
library(ggplot2)
library(shiny)
library(shinydashboard)
CountPlotFunction <- function(MyData)
{
MyPlot <- ggplot(data = MyData, aes(x = MyData)) +
geom_bar(stat = "count", aes(fill = MyData)) +
geom_text(stat = "count", aes(label = ..count..)) +
scale_x_discrete(drop = FALSE) +
scale_fill_discrete(drop = FALSE)
return(MyPlot)
}
# The data
var1 <- c("Russia","Canada","Australia","Australia","Russia","Australia","Canada","Germany","Australia","Canada","Canada")
var2 <- c("UnitedStates","France","SouthAfrica","SouthAfrica","UnitedStates","SouthAfrica","France","Norge","SouthAfrica","France","France")
var3 <- c("Brazil","Colombia","China","China","Brazil","China","Colombia","Belgium","China","Colombia","Colombia")
df <- data.frame(var1, var2, var3)
# The Shiny app
Interface <-
{
dashboardPage(
title = "Dashboard", skin = "yellow",
dashboardHeader(title = "Dashboard"),
dashboardSidebar(
sidebarMenu(
sidebarSearchForm(textId = "searchText", buttonId = "searchButton", label = "Search..."),
menuItem(text = "Analysis", tabName = "Analysis", icon = icon("dashboard")))
),
dashboardBody(
tags$head(includeCSS('www/style.css')),
tabItem(tabName = "Analysis",
fluidPage(box(title = "Choose the questions", status = "warning", solidHeader = TRUE, collapsible = FALSE, width = 12,
checkboxGroupInput(inputId = "ChooseQuestion", label = NULL, choices = colnames(df),
selected = colnames(df)[1])),
box(title = "Results", status = "warning", solidHeader = TRUE, collapsible = FALSE, width = 12,
uiOutput("ui_plot")))
)
)
)
}
Serveur <- function(input, output)
{
# gen plot containers
output$ui_plot <- renderUI({
out <- list()
if (length(input$ChooseQuestion)==0){return(NULL)}
for (i in 1:length(input$ChooseQuestion)){
out[[i]] <- plotOutput(outputId = paste0("plot",i))
}
return(out)
})
# render plots
observe({
for (i in 1:length(input$ChooseQuestion)){
local({
ii <- i
output[[paste0('plot',ii)]] <- renderPlot({
if ( length(input$ChooseQuestion) > ii-1 ){
return(CountPlotFunction(MyData = df[input$ChooseQuestion[[ii]]]))
}
NULL
})
})
}
})
}
shinyApp(ui = Interface, server = Serveur)
Add the following to your CSS file and it should work.
