Base44 testing

Form Conditional Logic Not Showing or Hiding Fields

Your Base44 form has conditional logic configured (show shipping fields when 'delivery' is selected, hide company fields for individual customers, display additional questions based on previous answers) but the conditions don't work. Fields that should appear stay hidden, fields that should hide stay visible, and the form behaves the same regardless of user selections.

Conditional forms are essential for creating clean, user-friendly interfaces that don't overwhelm users with irrelevant fields. When conditional logic breaks, users either see an intimidating form with too many fields, or they miss required fields that should have appeared based on their selections.

The issue is particularly disruptive when hidden fields have validation rules — users can't submit the form because a hidden required field has no value, but they can't see the field to fill it in.

Error Messages You Might See

Required field hidden but validation still triggered Conditional field not appearing after selection Form submitted with missing conditional data Field visibility rule has invalid reference

Common Causes

  • Condition references wrong field ID — The conditional rule points to a field that was renamed, deleted, or has a different internal ID than expected
  • Case sensitivity in condition values — The condition checks for 'Delivery' but the dropdown value is 'delivery' (lowercase)
  • Multiple conditions with wrong AND/OR logic — Conditions are combined with AND when they should use OR, making them impossible to satisfy simultaneously
  • Condition evaluates on form load only — The visibility check runs once on page load but doesn't re-evaluate when the user changes their selection
  • Hidden fields still requiring validation — Fields that are conditionally hidden still enforce their validation rules, blocking form submission

How to Fix It

  1. Verify field IDs in conditions — Check that the conditional rule references the correct field by its internal ID, not its display label
  2. Test with exact condition values — Select the exact value the condition expects and verify the field visibility changes. Check for case sensitivity
  3. Simplify conditions to debug — Reduce conditions to a single, simple rule (one field equals one value) and verify it works before adding complexity
  4. Disable validation on hidden fields — Ensure that when a field is hidden by a condition, its validation rules are also disabled
  5. Test all condition branches — Systematically test each possible value of the controlling field and verify the correct fields appear/disappear for each

Frequently Asked Questions

Why don't my Base44 form conditions work?

The most common issues are: the condition references a field by display label instead of internal ID, the comparison value has a case mismatch, or the condition doesn't re-evaluate when users change their selection. Start by testing with the simplest possible condition.

How do I prevent hidden fields from blocking form submission?

When hiding a field conditionally, also disable its required validation. Otherwise users can't submit because a field they can't see is marked as required. The validation should only apply when the field is visible.
