Configuration
Basic Settings
Placeholder Text Guide users with example input:- “Enter your email”
- “First name”
- “Your phone (optional)”

Validation
Email type inputs:- Validates format (name@domain.com)
- Errors appear only if the field is marked Required and the user tries to navigate to another screen without entering a valid email
- Integer only - Only whole numbers are allowed. Decimals (e.g., 3.5) are not accepted
- Min value and Max value - The minimum and maximum allowed values
- Exclusive: When set to Yes, the Min or Max value itself is not allowed
- Error message: Custom text shown for invalid values. You can provide your own message or keep the default one
Text Transformation
Automatically format input:| Transform | Input | Result | Use Case |
|---|---|---|---|
| Uppercase | john | JOHN | Promo codes |
| Lowercase | John@Email.com | john@email.com | Email normalization |
| Capitalize | john smith | John Smith | Names |
Using Input Values
Variables
Input values become variables using the element ID:Multiple Inputs
Collect complete information:Conditional Logic
Show/hide elements based on input:Mobile Optimization
Text inputs are optimized for mobile: Appropriate Keyboards- Email: Shows @ and .com keys
- Number: Numeric keypad only
- Phone: Large number keys
- URL: No spaces, quick slash
- Autocomplete for common fields
- Autocorrect disabled for emails
- Auto-capitalization for names
- Password managers integration
- Minimum 44px height
- Clear tap areas
- Proper spacing between fields
On mobile, use single-column layouts for forms. Side-by-side inputs
are harder to complete on small screens.
Form Design Best Practices
Progressive Disclosure
Don’t overwhelm users: Page 1: Email only Page 2: Name and preferences Page 3: Additional details This approach:- Increases completion rates by 30%
- Captures emails for abandonment recovery
- Feels less overwhelming
Field Order
Optimal sequence:- Email (easiest to provide)
- Name (personal but simple)
- Phone (more hesitation)
- Address (highest friction)
Labels vs Placeholders
Use both for clarity:- Label: “Email Address”
- Placeholder: “john@example.com”
