Conditional Logic

With conditional logic you can show or hide specific elements or a set of elements that are inside a column based on a field value.

What is conditional logic?

Conditional logic allows you to show or hide specific elements based on a other fields value. Whenever you have set a condition that was met and the method or action of this condition was to hide the element, it will no longer be visible to the user and will not be submitted by the form either.

When to use conditional logic?

You should use conditional logic to exclude fields from being submitted/saved. When a field or element is conditionally hidden it will not be visible to the user. (the field will not be send in emails, and will not be saved in contact entries, the form basically does not submit the field at all)

Whenever you wish to hide fields but still want them to be submitted to emails and saved in contact entries, instead use either a Hidden field, or put the fields in a Column and make the column invisible and make sure the column does not have any conditional logic enabled.

You can also use conditional logic to conditionally hide/show a Button element (submit button). For instance whenever you do not allow a user to submit the form based on specific input, you can conditionally hide the submit button and instead display a message to the user. You can do this by adding a Column element and adding a Button inside the column and applying the conditional logic on the column. The same thing you can do for the message to be displayed, you can add either a Heading or HTML element to display a message.

How to set conditions

A great example use case would be to have the submitter ask if they are registering as a person or as a business. Whenever they choose business, you will also want their Company name. But when they register as a person we do not want to display the Company name field because it is obsolete in this case. In this case we would apply the conditional logic on the company_name field to show when the submitter chooses to register as a business.

Given the above example with personal or business registration we will have a field called company_name that we only want to display when the user chooses to register as a business so they can enter their Company name. In this example we have the following fields:

• Radio button named account_type with the following options

  • Personal (with value: personal)

  • Business (with value: business)

• A text field named company_name

To apply the conditional logic on the company_name field edit the field and choose Conditional Logic from the dropdown menu.

You will now be asked if you want to Show or Hide the element when condition is met. In our case we will choose to Show the element when the condition is met.

Now we have to choose When to Trigger the condition(s) and show the field. You can choose from the below options:

• All (when all conditions matched) < this will show the element whenever all the conditions where met

• One (when one condition matched) < this will show the element whenever at least 1 condition was met

In our example it does not matter which one we choose, but for ease of use we leave it on the default option which is All (when all conditions matched)

The last step is to define the condition itself. You will be able to set the following options per condition:

• Field (in our example this would be the account_type field)

• Logic (in our example we will use the == equals condition, which is called the constructor) Possible constructors to choose from are:

  • ?? Contains

  • !! Not contains

  • == Equal

  • != Not equal

  • > Greater than

  • < Less than

  • >= Greater than or equal to

  • <= Less than or equal

• Value (in our example this would be business based on the account_type field value)

• Or/And method (each condition can have an OR or AND method to do an extra conditional check, but in our example we do not need it so leave it as is)
