Answer 1

Other way to do it is to pass style argument in the column function.

runApp(list(
        ui = shinyUI(fluidPage(
                h4("Download Options:"),
                fluidRow(
                        column(6, selectizeInput("plot_dl", "File Type", width="100%",
                                                 choices = list("PDF"="pdf","PNG"="png"))),
                        column(3, style = "margin-top: 25px;", downloadButton('plot1_dl', 'Left Plot')),
                        column(3, style = "margin-top: 25px;", downloadButton('plot2_dl', 'Right Plot'))
                )
        )),
        server = function(input, output) {
        }
))

Answer 2

Found an ad-hoc fix with margin-top: 25px in the style tag...

library(shiny)

runApp(list(
  ui = shinyUI(fluidPage(
     h4("Download Options:"),
     fluidRow(
       column(6, selectizeInput("plot_dl", "File Type", width="100%",
                                choices = list("PDF"="pdf","PNG"="png"))),
       column(3, downloadButton('plot1_dl', 'Left Plot')),
       column(3, downloadButton('plot2_dl', 'Right Plot'))
     ),
     tags$style(type='text/css', "#plot1_dl { width:100%; margin-top: 25px;}"),
     tags$style(type='text/css', "#plot2_dl { width:100%; margin-top: 25px;}")
  )),
  server = function(input, output) {
  }
))
