Is it possible to use a spinner to enter data into a text or a decimal field?
Don't understand the question.
If you mean a numeric input field, you can select Number type in the Properties tab:
If you wanted to constrain the number range, you could include a Load rule in Form Options like:
The control itself does not show up/down arrows, nor does it prevent manual entry of out-of-range values. That might need a Jira ticket to resolve.
HTML input type=number controls are also not supported in Internet Explorer.
What I wanted to appear on a numeric field, were up/down arrows.
You can get text fields to look like this, with some effort, that also works in IE:
That styling required a few different steps:
This is only really for a test... you would need to be very careful that the JQuery UI inclusion doesn't break existing behavior. It might also be problematic for multiple fields on the same row.
