    Can I limit a specific field so that when it reaches a certain number it becomes disabled?

    Asked by mia1003 on November 03, 2015 at 10:37 AM

    I have only ordered a set amount of books to be ordered.  I would like to disable the field when that number of books is reached.  Can JotForm do that automatically or do I just need to watch  my submissions and disable it when it reaches that number?

    Our invetory widget sounds like it is exactly what you are looking for:


    This will allow you to set a total amount of product available and once it reaches 0, it will no longer allow people to select that option.

    If you have any further questions, let us know and we will be happy to help.
