Field Rules

Press the Add rule button and establish a field rule. In the first dropdown list, choose the field that will affect your form’s behavior. Then specify the criteria it needs to meet to trigger changes and decide if it is going to show or hide another field (that will be designated in the last dropdown list). Preview your form at all times and delete the rules that you don’t want to use anymore.

How can field rules ease the use of online forms for your visitors?

Too many form fields could decrease the conversion of your online form. Having field rules set in the right way could avoid this problem by giving your form users a dynamic form to submit. Field rules are the perfect solution for complex order forms, photo contest forms, event registration forms and many more.

Some options would be irrelevant for your form users to view if they have selected others instead. Take for example a food delivery order form. If a customer selects macaroni and cheese, two radio buttons will appear under the field with the options ‘more macaroni’ and ‘more cheese’. If the same customer selects another menu, then the two options will no longer be displayed on the form. Less content might just prove to be more engaging.


  1. Steve Priestley says:

    I want when someone selects a certain field in a drop down section for 4 more question fields to become available.
    For example. my dropdown menu says
    Outdoors on Grass
    Outdoors on Hard Surface
    Indoors on Hard Surface
    When they select Indoors option I want them to see 4 other options to complete. I don’t want other who don’t want everyone to see this options unless they select the ones I want.
    Please can you help.
    Plus Can I link my google calendar to certain fields, or/and my form when completed sends to the corresponding calendar date in google calendar?
    Thanks for you assistance.

    • Hello Steve!

      You can easily create this scenario with field rules by showing some fields (options) only when a specific options is selected in the dropdown field. To accomplish this, hit the Add Rule button and select the dropdown field in the first selector. Next, put the operator “is” and type in the option that is also available in the dropdown. Hit Continue and select “Show” in the first selector that appear and in the last selector simply check the fields from the list.

      Here’s a documentation that might help:

    I can’t get more than one rule to trigger the show/hide field.

    I have a text box that doesn’t have any conditions on it, just an ordinary text box. When someone types something in it, i would like to have a rule that another text box will appear under it. The problem is that I can’t predict what the person will type as it’s an open ended question. Is there a way to have a rule where if someone types anything, any character or number, instead of specifying a specific letter or word or number that the rule will work?

    • Hello Lisa!

      Could you please specify a scenario that describes what you want to do? What you suggest is a bit complex. Perhaps there is a way to achieve the same results, but much easier.
