QUESTION
I would like to create a Shiny document which shows two grobs alongside one another and would like the text inside each grob to be the selected value of a sliderInput.
I am able to easily output two grobs side-by-side in a non-reactive context (first example below) but obviously cannot extract the slider value. However, when I try to output them inside a renderPlot
reactive context, I am able to extract the slider value, but only the second grob shows up and the connection arrow is not visible.

- Use

rank
to get the hidden blank nodes to line up with exclusion boxes.
Hope this is helpful.
