Hi, Is there a way where I can restrict number field box to display j

To just display a number you can use a textfield and the text() function for formatting.

thanks for reply but thats not what I am looking for. Let me try to explain it: if we want to enter 16 digit credit card number then I want the first box of 4 numbers to have box size of 5 characters only.

Please refer to the screen shot.

So you want the input field to be smaller of size. That is not possible AFAIK.

You might be able to "fake" that using a single row grid. But I don't know if it's possible to have a grid without headers.

I did a small test.

HI you can use validation on the field like below:
a!textField(
label: "INPUT",
labelPosition: "ABOVE",
value:ri!input,
saveInto: ri!input,
refreshAfter: "UNFOCUS",
validations: if(len(ri!input)>4,"Not more than 4",""),
align: "LEFT"
)

thanks guys for your valuable suggestion.

you can also use complicated variations in the saveInto: field and have the box refuse to accept additional characters - but it's difficult to get it to work just right.
