Number field quick input

[OOoo]

I have a custom field, which type is number, how can I do add and subtract with click, like image below.

I don't think that something like this is possible.
Maybe you could give us some more information about your use case, to find another suitable solution?

In my team, when we do the standup meeting, we use an all-in-one PC(windows). The PC's screen is touchable, we can do some simple edit on the meeting.

Jira original number field need to input number with soft keyboard, which is a little tricky.

Can I do number add or subtract with buttons?

Ok, I get it. So I guess the easiest way would be, to handle this via workflow buttons.

And then you have to add a addition/subtraction to the corresponding post function.
The only downside to this solution is, that you will get a reload with every single transition.

Another solution could be a single select list. But this only makes sense, if the amount of numbers is limited.

Thanks for your reply.

These two solutions can not make the add operation more easier on sprint screen.

I need do add or subtract on the screen, which I think should customize the input tag generated by Jira itself, Is there any ways to do the customization?

Is there any way to change the form generated after click the custom field?

The input label have an attribute "type = text", if I change the type to number, the input label got a little button which can do add and subtract.

Is there any way to change the input label generator?
