Sometimes there are too many rows in a data table to display on one page and scrolling is not the most user-friendly way to solve this. This examples provides a way to layer information into a overlay which can be accessed by clicking a link in a data table.

Add an an extra column for the data in your table and attach a Shiny event listener to it to return its index
dat <- iris %>% mutate(More = paste0('<span><a href="javascript:void(0)" onmousedown="',
'Shiny.onInputChange(\'DTClick\',[', 1:n(), ',Math.random()]);',
'event.preventDefault(); event.stopPropagation(); return false;">
<font color="grey">●●●</font>
</a></span>')
)
)
Listen for the click and show the overlay
observeEvent(input$DTClick, {
showModal(modalDialog(
title = paste0("You just clicked row ", as.numeric(input$DTClick[1])),
dataTableOutput("modalContent"),
size = "l",
easyClose = TRUE,
footer = NULL
))
