Conditional Logic & Branching
Build smart forms that adapt in real time — show the right questions, skip irrelevant ones, and guide each respondent down the path that matches their answers.

Forms with conditional logic see up to 42 % higher submission rates (internal FormFlow benchmark, Q3 2024, 1,800 live forms). When respondents only see questions that apply to them, drop‑off plummets — and your data quality goes up.
FormFlow's logic engine evaluates conditions on every keystroke and every selection. No page reloads, no JavaScript knowledge required. Set a rule in the visual builder and the form does the rest.
Logic That Fits Your Workflow
Multi‑Step Quizzes & Assessments
Branch respondents into different result pages based on their answers. Example: a 12‑question skincare quiz by DermCo routes users to one of five product recommendations, each with a tailored checkout link.
Dynamic Pricing & Cost Calculators
Show or hide add‑on fields as selections change. A roofing contractor's estimate form reveals snow‑guard options only when the user selects a metal roof and a pitch over 6/12 — keeping the quote accurate and the form clean.
Compliance & KYC Workflows
Trigger document‑upload fields when a user selects "Business" entity type or enters a high‑risk jurisdiction. FinBridge uses this to collect W‑9 forms for U.S. entities and EDD forms for European ones — automatically.
Event Registration with Tiered Tiers
Unpack diet‑restriction checkboxes only when "In‑person" attendance is chosen. Reveal parking‑pass fields based on arrival time. TechSummit 2025 reduced no‑shows by 18 % after adding location‑specific questions.
IT Helpdesk Triage
Route tickets by department, severity, and device type. If "Laptop" + "Won't Power On" + "Under Warranty" are selected, the form auto‑assigns the ticket to the Hardware team and skips software‑troubleshooting questions.
Onboarding Surveys
Ask follow‑up questions based on initial responses. When a new SaaS user selects "Marketing" as their role, a second wave of questions about campaign tools and integrations appears — giving your CS team actionable context from day one.
Visual Rule Builder — No Code Required
Every condition is a simple sentence: "If [field] [operator] [value], then [action]." Chain multiple conditions with AND/OR, reference calculated values, and group rules into named branches for clarity.
Supported operators: equals, does not equal, contains, starts with, greater than, less than, is empty, matches regex.
Actions: show, hide, make required, make optional, set default value, jump to page, end submission.
Advanced features: evaluate on change vs. on submit, cross‑field calculations, branching to external URLs, and logic‑group inheritance for multi‑page forms.
The builder includes a live preview panel: as you add rules, a simulated respondent walks through the form so you can verify every branch before publishing.

Solar Installation Quote — SunPath Energy
Page 1 collects roof type and location. If "Flat Roof" is selected, the form skips racking questions and jumps to a structural‑assessment upload. If annual usage exceeds 1,200 kWh, a battery‑storage section appears with capacity selectors. The final page shows an instant estimate range pulled from a lookup table.
Clinical Trial Screening — Meridian Health
A 30‑question eligibility screener narrows to 8 questions for most users. Exclusion criteria (e.g., "pregnant," "current medication X") trigger an immediate end screen with a polite disqualification message and a link to alternative studies. Qualified leads are routed to a scheduling calendar.
B2B Procurement Request — Northgate Manufacturing
When the "Estimated Spend" field exceeds $10,000, the form reveals an approval‑chain section requiring a manager email and cost‑center code. For IT purchases above $50,000, a CFO sign‑off field becomes required. All rules are grouped under "Approval Logic" for easy auditing.
Multi‑Language Customer Feedback — Travelio
The first question asks for the booking language. Based on the selection, the entire form switches to that language (FormFlow supports 28 languages). If the user rates their stay below 3 stars, an open‑text "What went wrong?" field appears with a dedicated Slack alert to the guest‑relations team.
