We have a requirement where if checkbox is checked then we need to change button label within Button

Again… simply have several button sets and render conditions for each is your best bet )

I think David’s solution offered is acceptable. You could also use “sections” merge syntax to create truthy falsy logic on which label to display on render.

I think the challenge with this is that the merge will only evaluate on render, it wont reevaluate by default if a box is checked or unchecked. But you could use this if the button is on a different page or you could run a snippet to rerender the merge.

But again, David’s solution may be the simpler of the 2, if you build your button actions into reusable action sequences.

Thanks!
