@Itskiprotich have you been facing issues with the up/back button that currently cancels the questionnaire collection?

@shelaghm FYI

[Itskiprotich]

@omarismail94 the up/back button works well. However, for uniformity design-wise, I find it ideal to have both submit and cancel buttons.

Thanks @Itskiprotich for raising this issue and creating the PR.

@shelaghm @rowo @joiskash @kunjan8794 please note the change that is being proposed in this ticket. I do feel this is a very reasonable feature, but also something that would require an option to turn it on/off.

One thing I'm not totally sure is just whether this is something that should be default to on or off? Any thoughts?

Also I don't know if it's a good idea to limit this to single page questionnaire... ? should paginated questionnaires also have an option to include a cancel button? if so should it be on the first page or every page? if every page how do we position this button together with the prev/next buttons?

This looks good! I would vote for default on

Re: paginated

I've mocked up some options so we can discuss what the best option is.

My preference is for A, not including a cancel button on paginated questionnaires. The existing arrow serves the same action of exiting the questionnaire.
B, I worry about adding a third button next to back/next navigation buttons and I think it might add confusion. Depending on phone size/text size the buttons are also too close to each other and worry about accidental taps.
C, I believe breaks some of the Android standard navigation patterns, so not sure if this a good idea either.

What do you all think? Other options we should explore for this?

Discussion w/ Jing and team:

• Default is A, and if showing the cancel button is on, then show B
• Also show a cancel dialog with "Do you want to exit the questionnaire?" Yes/No.

@shelaghm I have updated the feature to include the confirmation dialog within the SDC.
