You may need to create a form out of some Data Master's fields. This is fast and easy with Justinmind Prototyper with a simple 'drag and drop'.
To create a form using all the fields from a Data Master, just drag the Data Master from the Data Master's panel and drop it on the canvas. A form will be created with Data Master's field names as Texts with a corresponding input for each of them.
If you want a form with only some of the Data Master's fields, select the required fields on the Data Master's panel and drag and drop them on the canvas.
