Collapse Shinydashboard box from server.R

[Kevin van Blommestein]

First off, thank you for Shinydashboard, it has really made things easier.

I would like to start my Shiny app with a box collapsed and when the user uploads a file, the box uncollapses. I tried to use Javascript to click the collapse button, but there is no id for the button. Is there an easy way to achieve this or should I just stick to jumping between multiple tabs using updateTabsetPanel?

Sorry, there isn't a simple way to do this right now. You could still use Javascript to trigger a click event -- you just need to use the right selector.

This will find the first box with a collapse button and trigger it.

  $('.box').find('[data-widget="collapse"]').click()

This still isn't ideal, because the box itself doesn't have an ID, so if you have multiple boxes with collapse buttons, you'll have to do a little more work to pick out the right one, by numeric position, or perhaps by finding one with a particular title associated with it. This is still all doable with jQuery, but will require a little more work.
