LiveView can handle that pretty well, you can setup a click or validation handler for your live view / component. It then hits the handler function on the backend and you can have the component updated in place. Since it only sends the diffs down it's pretty efficient on the round trip, at least not something to worry about compared to the hundreds of api calls most SPA's will make. So the flow is 1) click the checkbox 2) call sent across the open socket 3) backend does it's logic to figure out what it needs to do 4) backend returns the small diff of changes 5) frontend alters dom.
