[forms-devel] forms-devel Digest, Vol 4, Issue 2

Fri Aug 12 07:56:56 UTC 2016

Hello all and Adam,

Thank you for you opinion.

I agree that the way using ListView you mention can be another way to
provide a multiple selection of items.
I also agree that this approach can provide better UX for ListView.

However, how about considering the scenario that the number of item is one
or two?
If the number of item is one or two and app user can select one status
between 'Checked' and 'Unchecked' in each item,
Should app developer provide this UX with ListView?
The development process of an app that this UX is provided with ListView
takes more time than the procedure using a simple checkbox.
The app should include more code line than an app using a simple checkbox.

As you already know, checkBox have function to indicate two states which
are 'checked' and 'unchecked' with text
as well as function to provide multiple selections of items.
So, checkBox could be useful control for  providing user's selection
between 'checked' and 'unchecked' about one or two items with text.

Also, is this link(https://material.google.com/) Google Material Design
Guidelines you mention on a previous email?
Actually, it is a little hard to find some opinion that guideline specially
discourage checkbox.
Instead, this design guideline describes well that checkbox is one of
controls for allowing the user to select options.
I'd like to share two link about checkbox in Google Material Design
Guidelines.
- https://material.google.com/components/selection-controls.html#
- https://material.google.com/components/lists-controls.html#
These two link describe definitely how checkbox can be useful for providing
various UX to user.

Thank you for sharing your opinion about checkbox again.

Best regards,

- Rina You
