How to use conditional logic to show/hide form fields on 123FormBuilder?

To use conditional logic to show or hide form fields, go to the Rules section of your form within the form builder. Tick the option Enable field rules, under the Field Rules tab.

Afterward, click on the Add Rule button to start setting up your rules.

Add a field rule

The first condition (IF) will appear on the page along with some dropdowns, a Cancel, and a Continue button.

Cancel Continue buttons

In the first dropdown, select the field you want the rule to apply to. Then, select the condition. Depending on the field type selected previously, there are different conditions. For choice fields, you can use the conditions is checked or is not checked. However, for input fields, you’ll need to select a condition from the dropdown list and provide a value on the right. For example, age restriction: If age is less than 21, then don’t show the list of alcoholic beverages on the form.

Notice the grey button on the right with the plus sign. Press it to create a new condition if needed. It is connected to the previous condition with one of the available connectors: OR and AND. Use this button if you want to set multiple conditions within the same rule.

Add a new condition

Next, hit Continue and select one of the two existing actions: Show or Hide. In the end, select the field or fields you want to show or hide after the condition has been met on the form.

Important Note

Hit Finished to add and apply the rule to your online form.

You can always disable the rules by clicking on the Enable field rules checkbox. The rules will remain the same and will be currently unavailable. At any time you can come back and turn them back on.
