title: How to vertically align multiple radio button columns in Shiny R?
body: <hr />
  <p>I would like to create a list of radiobuttons inside a tabItem in Shiny.  If I set inline = TRUE, it puts everything on horizontal lines, but nothing is lined up neatly.  How would I vertically align the radio buttons in the following code, while defining the number of columns I want?</p>
  <pre><code>        # Descriptive Plots tab content
      tabItem(tabName = 'descrPlots',
              fluidRow(
                column(width = 2,
                       box(
                         width = NULL, background = &quot;aqua&quot;,
                         radioButtons('radio_Descr',label = h3(&quot;Choose a Variable to View:&quot;),
                                      choices = list('TA' = 'TA','PP' = 'PP', 'US' = 'US', 'UD' = 'UD', 'UE' = 'UE',
                                                     'UG' = 'UG', 'UH' = 'UH', 'XR' = 'XR', 'RW' = 'RW', 'PA' = 'PA', 'TB4' = 'TB4',
                                                     'TV2' = 'TV2', 'TV4' = 'TV4', 'TV8' = 'TV8', 'TV20' = 'TV20', 'TV40' = 'TV40', 
                                                     'MV2' = 'MV2', 'MV4' = 'MV4', 'MV8' = 'MV8', 'MV20' = 'MV20', 'MV40' = 'MV40',
                                                     'VB' = 'VB', 'TA40' = 'TA40', 'TA120' = 'TA120', 'SD' = 'SD'), inline = TRUE, selected = NULL)
                         
                       )
                )
              )
      )

  <p>I would think I could wrap the radio buttons in a tagList like the following, but what is the code I need to actually get it to work?  I am not an HTML or CSS programmer, and can't follow other questions dealing with this very well.  All this code is, so far, in the UI part of the Shiny app, not the server part.  Maybe that should be changed, too?  Thank you.</p>
  <pre><code>       box(
            width = NULL, background = &quot;aqua&quot;,
              tagList(
                      tags$style(type = 'text/css', '#radiobuttons .multicol{-webkit-column-count: 2; 
                                   -moz-column-count: 2; column-count: 2;}'), 
                      div(id = 'radiobuttons',
                            radioButtons('radio_Descr',label =
  </code></pre>
