Conditional logic in Zoho Forms lets you define rules that evaluate the current value of one or more fields and then trigger an action: show a field, hide a field, mark a field required, or skip to a specific page. Rules are built in the form builder under the Rules tab using a condition-action structure. Multiple conditions can be combined with AND or OR operators, and a single field can trigger more than one rule.
Use conditional logic whenever your form has branching information needs. A service request form might show a warranty details section only if the customer selects a specific product category. A job application can reveal a work-permit field only for applicants who indicate they are not Indian nationals. Avoid building overly complex rule chains on a single form; beyond a certain depth, it is cleaner to split into separate forms with different share links.
Rules execute client-side in the respondent’s browser, so they depend on JavaScript being enabled. Hidden fields are excluded from required-field validation, meaning a hidden required field will not block submission. Rules evaluate in the order they are listed; conflicting rules can produce unexpected results, so test the full form thoroughly before publishing. Conditional logic is available on paid Zoho Forms plans; the free plan has limited rule support.
In Zoho Forms, fields hidden by conditional logic do not submit their stored values by default. If a respondent first answers a hidden field and then the field is hidden by a later choice, the value may or may not persist depending on the rule configuration. Always test with representative data paths to confirm the behaviour before going live.
Yes. Zoho Forms supports page-skip rules in multi-page forms, allowing a respondent’s answer to jump them from page 1 directly to page 3, bypassing page 2. This is configured in the same Rules interface. Page-skip logic must be planned carefully to avoid dead-end paths where the respondent cannot reach the submit button.
