Sub label is not an option in the field of a Date Picker widget.

Is there any way I can provide a CSS Code to add a sub label? If not, what course of action should I take to add a small note (except the Hover Text)?

You can add a Text field and move it by using CSS to be like a sub-label.

To do that, please follow:

1. Add Text field to your form:

2. Edit the HTML and place the text of your sub-label:

Then, copy and paste the below CSS to your Custom CSS field:

#text_12 {

margin-top:-40px!important;

}

Here is my clone of your form:https://form.jotform.com/70016024872953 feel free to check it out.

Could that work for you?

Please let us know.

Thank you!
