Trying to create a bulk select with repeater table

I am trying to create a table with multi select and bulk editing the status (Present is default) and am not sure how to even approach this. The table is a repeater widget with column data. I want the top bar to be able to update the status for however many rows are checked. Any help is appreciated.

This kind of thing is kind of complex to explain - I’d suggest you upload your RP file. Broadly, you need to track whether an item is checked or not within your repeater and mark the row when it is, then update marked rows and unmark all rows when you use the global attendance status button.

This post is a great introduction to repeaters. Also the videos on repeaters in this playlist are very useful.
