What is Branching Logic?

Conditional logic, also known as branching logic, enables your form to respond dynamically to user decisions. The form can show or hide specific fields based on user selection, simplifying the process and eliminating unnecessary inputs.

Example

If a user selects “Contractor” from a dropdown, fields related only to contractors will appear. Other sections, such as full-time employee information, remain hidden.

Why Use Branching Logic in SharePoint Forms?

Key Benefits

  • Simplifies the User Experience: Only questions relevant to the user are displayed.
  • Reduces Entry Errors: Hidden fields can’t be filled incorrectly.
  • Improves Data Quality: Ensures accurate and relevant inputs.
  • Saves Time: Avoids unnecessary scrolling or input.

Limitations

  • Limited Logic Scope: Only supports simple conditions; complex logic (e.g., AND/OR combinations) requires Power Apps.
  • No Backward Conditions: You can't reference future responses to adjust earlier fields.
  • Basic Customization: The built-in SharePoint form designer limits visual layout and advanced actions.

Use Case: IT Helpdesk Ticket Form

Let’s say you’re building an IT helpdesk form. Based on the selected Issue Type, you want to display only the relevant fields.

  • Hardware: Show Device Type and Serial Number.
  • Software: Show Software Name and Version.
  • Network: Show Location and Network Issue Description.

Always show: Priority and Description
