title: Change shinydashboard box width
body: <p>I'm quiet new to R but am trying to design a UI which has a main box going across the top of the main body with two smaller boxes underneath. At the moment everything I have tried seems to display it in each corner of the main body. Image attahced. The subsection of my code is below:</p>
  
  <pre><code>  dashboardBody(
          fluidRow(
            box(plotlyOutput("Map"))),
          fluidRow(
            box(plotlyOutput("Chart")),
            box(tableOutput("Table")))
          )
        )
  </code></pre>
  
  <p>I have tried width and height (100%) etc but now joy.</p>
