title: How to remove the footer on a bsmodal
body: <p>I've been looking around, and the documentation I found says they added a footer and button.close argument to the bsmodal function, but it doesn't seem to work. Does anybody know how to remove (or even just alter) the close button, and/or remove the whole footer part of the bsmodal popup? </p>
  
  <p>Here's a working test app. I added a few css elements in case somebody might be interested in seeing that applied (I use the adjustments in my own actual app) </p>
  
  <p>Info was found <a href="https://github.com/ebailey78/shinyBS/issues/25" rel="nofollow noreferrer">here</a> : if I apply this as in the example, it just prints false in the popup.</p>
  
  <pre><code>library(shiny)
