🧠 How do I add logic to my form?
Form logic lets you create smart, dynamic forms that react based on user input.
With OpnForm, every field can have its own logic rules to show, hide, require, or make optional based on specific conditions.
⚙️ Available Logic Actions
You can trigger four types of actions when conditions are met:
- ✅ Make field required
- 🚫 Make field optional
- 👀 Show field (if currently hidden)
- 🙈 Hide field (if currently visible)
✨ How to Set Up Logic for a Field
- Open your form editor.
- Click the Settings icon next to the field you want to configure.
- In the modal that appears, open the Logic section.
- Set your conditions (for example: If answer to Question 1 is Yes).
- Choose the action(s) you want to trigger.
- Click Publish— and you’re done! 🎉
Your form will now respond dynamically based on user input.
📅 Date Logic Conditions
Date logic lets you create time-sensitive form behavior based on how recent or upcoming a selected date is. This is useful for things like deadlines, reminders, or event scheduling.
⏰ Available Date Logic Options
Condition | Description | Example |
|---|---|---|
At Least X Days Ago | Triggers when the date is X or more days in the past. | “At least 7 days ago” → matches anything older than a week. |
At Least X Days From Now | Triggers when the date is X or more days in the future. | “At least 7 days from now” → matches anything a week or more away. |
Within Past X Days | Triggers when the date falls within the last X days, including today. | “Within past 7 days” → matches dates from last week through today. |
Within Next X Days | Triggers when the date falls within the next X days, including today. | “Within next 7 days” → matches today through next week. |
💡 Example Use Cases
- ⚠️ Show a “Late Submission” warning for dates more than 30 days in the past.
- 📝 Require additional information for events happening within the next 7 days.
- 🚫 Hide certain options for events too far in the future.
Date-based conditions make it easy to create responsive, time-aware forms that adapt automatically.
❓ FAQ
Why don’t I see the “Show” or “Hide” options?
These actions are context-based:
- 🔒 “Show” only appears if the field is currently hidden.
- 👁️ “Hide” only appears if the field is currently visible.
If you don’t see one of these options, make sure the field is in the correct state.
🎥 Example: Showing a Hidden Field
Here’s a quick demo using the “Message” input field.
In this example, the “Message” field starts off hidden and only appears when the user selects “Option 1” from a Select field.
