fillRow
fillRow(..., flex = 1, width = "100%", height = "100%")
fillCol(..., flex = 1, width = "100%", height = "100%")
Arguments
... | UI objects to put in each row/column cell; each argument will
occupy a single cell. (To put multiple items in a single cell, you can use
tagList or div to combine them.) Named
arguments will be used as attributes on the div element that
encapsulates the row/column. |
---|---|
flex | Determines how space should be distributed to the cells. Can be a
single value like 1 or 2 to evenly distribute the available
space; or use a vector of numbers to specify the proportions. For example,
flex = c(2, 3) would cause the space to be split 40%/60% between
two cells. NA values will cause the corresponding cell to be sized
according to its contents (without growing or shrinking). |
width, height | The total amount of width and height to use for the
entire row/column. For the default height of "100%" to be
effective, the parent must be fillPage , another
fillRow /fillCol , or some other HTML element whose height is
not determined by the height of its contents. |
Description
Creates row and column layouts with proportionally-sized cells, using the Flex Box layout model of CSS3. These can be nested to create arbitrary proportional-grid layouts. Warning: Flex Box is not well supported by Internet Explorer, so these functions should only be used where modern browsers can be assumed.
Details
If you try to use fillRow
and fillCol
inside of other
Shiny containers, such as sidebarLayout
,
navbarPage
, or even tags$div
, you will probably find
that they will not appear. This is due to fillRow
and fillCol
defaulting to height="100%"
, which will only work inside of
containers that have determined their own size (rather than shrinking to
the size of their contents, as is usually the case in HTML).
To avoid this problem, you have two options:
- only use
fillRow
/fillCol
inside offillPage
,fillRow
, orfillCol
- provide an explicit
height
argument tofillRow
/fillCol
Examples
# Only run this example in interactive R sessions.
if (interactive()) {
ui <- fillPage(fillRow(
plotOutput("plotLeft", height = "100%"),
fillCol(
plotOutput("plotTopRight", height = "100%"),
plotOutput("plotBottomRight", height = "100%")
)
))
server <- function(input, output, session) {
output$plotLeft <- renderPlot(plot(cars))
output$plotTopRight <- renderPlot(plot(pressure))
output$plotBottomRight <- renderPlot(plot(AirPassengers))
}
shinyApp(ui, server)
}
