title: How to use checkbox:nth-child with inline checkboxGroupInput?
body: <p>In following <a href="https://stackoverflow.com/questions/39276632/shiny-r-how-to-disable-checkboxgroup-input-after-it-is-clicked">this question</a> if the <code>checkboxGroupInput</code> has <code>inline=TRUE</code> then <code>disable(selector=&quot;#a .checkbox:nth-child(1) label&quot;)</code> will no longer disable the option.  Is there a tweak to the selector string?  I tried changing it to <code>checkbox-inline</code> but that didn't work.</p>
