How can I mask an input field?

I have a weird request. There is a colon separating two sections. The colon needs auto entered when text input expands to next line. 

Is it possible?

Thanks eshu153

Hello Eswari - Can you be more specific on what you're referring to? From how you described it, looks like you need a sort of an Input Mask so the colon remains on the input field when your users/respondents are filling it out. If I got that right, follow the guide that I'm linking below.

In case we misunderstood your question, just get back to us with a bit more info and a clearer description of what you're trying to do so we can better assist you.

I am talking about outside text box. Let me attach a screenshot.
If you look at the below screen, the colon symbol on right side should
automatically entered into next line when the defendant field on left
expands. Is this achievable?
Thanks and regards

Hello Eswari,

Unfortunately it is not possible to dynamically increase the height of space below the textbox. Though I am not sure what is your exact requirement but I would suggest you to please take a look at our "Narrative Fields" and "Passage Test" widgets and see if that fits into your requirement.

Thank you!
