How to Use Conditional Options for Shopify Product Customization

November 3, 2026 · Conditionals, Options

Not every shopper wants engraving. Showing text fields on every PDP creates noise and remake risk (“I didn’t mean to personalize”). Conditional options ask a question first—then reveal personalization fields only when the shopper opts in.

Souvely Product Personalizer supports conditional questions on a personalization rule (AddOn). Affirmative answers can reveal front and/or back surfaces before text or image UI appears. Answers travel with the order as line-item properties.

What conditionals do (verified product behavior)

Merchant configures optional Conditional questions in the rule editor (Questions step).
Primary merchant UI path: yes/no questions (e.g. “Add engraving?”).
Each question can reveal front, reveal back, or both when the shopper answers yes.
Until the gate passes, those sides stay hidden in the storefront widget.
Answers are recorded on the cart line for ops.
Available on Free, Starter, and Unlimited (conditional_options capability).
Optional fee (cents) on a question is editable on paid plans; Free can ask questions but cannot charge shoppers at checkout. Conditional fee cents are quoted server-side and are not auto-mapped to Shopify fee variants unless you map them to a fee product later.

When to use them

Use case	Example question	Reveals
Optional engraving	“Add engraving?”	Front text
Optional second side	“Also personalize the back?”	Back
Gift vs blank	“Is this a gift with a custom message?”	Front
Skip personalization entirely	“Customize this item?”	Front + back

Skip conditionals when every buyer must personalize (always-on monogram SKUs)—keep the fields visible by default.

Setup path

Install Souvely Product Personalizer and enable Souvely storefront.
Create or open a personalization rule with front and/or back enabled as needed.
Open the Conditional questions (optional) step in the rule editor.
Click Add yes/no question, write a clear label, and check Reveals front / Reveals back.
On Starter/Unlimited, optionally set fee (cents) for an affirmative answer—then plan how that maps to a checkout fee product if you need automatic charging.
Save, assign the rule, and test on the storefront: fields stay hidden until “yes”; “no” keeps them closed.

Storefront behavior shoppers see

Question block appears above personalization fields.
Yes/no controls collect the answer.
Affirmative answers reveal the configured side(s); preview and text/image UI follow your rule.
Add to cart includes the question label + answer with other personalization properties.

Common mistakes

Mistake	Fix
Question with no reveals	Check Reveals front and/or back
Enabling back reveal when back is disabled on the rule	Enable the side first
Expecting conditional fee cents to appear as checkout lines automatically	Map to a fee product on paid plans, or use per-side text/image fees
Vague question copy	Use a single clear yes/no (“Add engraving?”)
Forcing always-on text behind a useless gate	Remove the question for must-personalize SKUs

Hypothetical example

Example (illustrative): A jewelry merchant sells the same bar necklace blank and personalized. One yes/no question—“Add engraving?”—reveals front text only when shoppers say yes. Blank buyers add to cart without fields; gift buyers type a name, see the preview, and checkout with the answer on the line item.
