fillRow {shiny} | R Documentation

## Flex Box-based row/column layouts

### 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.

### Usage

    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.

### 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 of `fillPage`, `fillRow`, or `fillCol`

- provide an explicit `height` argument to `fillRow`/`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)

    }
