How to define logic in multiple-choice (checkbox) questions?

When respondents can select several options in one question, each choice may require its own follow-up questions. Porsline’s online form builder lets you combine multiple selections with Logic so each respondent moves through the question groups relevant to the options they selected.

This video uses an online order form to show how a checkbox-style question can control several possible paths.

What You Will Learn

• Allow more than one option to be selected.
• Set minimum and maximum selection limits.
• Connect each selected option to its relevant question group.
• Continue the Logic path when respondents select several options.
• Direct respondents to the appropriate final step.
• Combine the workflow with calculations when values need to be totalled.

When Checkbox Logic Is Useful

Checkbox Logic is especially useful when one answer can lead to several relevant follow-up paths. It helps keep the form focused while still collecting the additional details required for every option a respondent selects.

Build Product or Service Order Forms

Suppose a customer selects several products or services in the same form. With marketing forms and surveys, Logic can show only the questions related to those selections instead of presenting every product question to every customer.

The video demonstrates this with several fruit options, separate question groups and calculations that contribute to the final order value.

Collect Details for Multiple Event Choices

A participant may register for several sessions, workshops or activities at once. An event registration form can use multiple selections to identify their choices and then display the follow-up questions required for each selected activity.

The key difference from a single-choice Logic path is that more than one branch may need to be visited before the respondent reaches the End Page.

Before publishing, test combinations of selections rather than previewing only one option at a time. This helps confirm that respondents move through every relevant group in the intended order.
