title: R shiny making sub panels
body: <p>Is there a simple solution to making tab panels within the main tab panels created in R shiny?</p>
  
  <p>Here is how I create the main panels:</p>
  
  <pre><code>mainPanel(
    tabsetPanel(id = "tabSelected",
      tabPanel("Tab1", uiOutput("Tab1")),
      tabPanel("Tab2", uiOutput("Tab2"))
  </code></pre>
  
  <p>I wanted to make new tabs within "Tab1" for various plots I would like to show. I attempted to nest the tabsetPanel function but that doesn't work. Thanks!</p>
