# Conditional Logic

Show or hide fields based on how a customer answers a previous question. This keeps your form short and relevant — customers only see the questions that apply to them.

For example, if someone selects "HVAC" as their service type, you can show a follow-up question about their AC unit brand. If they select "Plumbing," you show a different set of questions instead.

## How It Works

1. Open your form in the form builder.
2. Click the field you want to show or hide conditionally.
3. In the field settings panel, find the **Conditional Logic** section.
4. Click **Add Condition**.
5. Set up your rule:
   * **When** — pick the field that triggers the condition (for example, "Service Type").
   * **Is / Is Not / Contains** — pick how to compare.
   * **Value** — pick the answer that triggers this rule (for example, "HVAC").
6. Choose whether to **Show** or **Hide** the current field when the condition is met.
7. Click **Save** and preview your form to test it.

![show conditions (step 2)](/files/5ZcsVLfZOu8yGwNSNjAG)

## Examples

* **Show "AC Unit Brand"** only when Service Type is "HVAC."
* **Show "Number of Fixtures"** only when Service Type is "Plumbing."
* **Show "Roof Type" dropdown** only when Service Type is "Roofing."
* **Hide "Upload Photos"** when the customer selects "Just a question, no service needed."

## Tips

* **Build your form without conditions first**, then add them after all your fields are in place.
* **Test every path.** Preview the form and try each answer to make sure the right fields show up.
* **Don't over-complicate it.** One or two conditions per field is usually enough.
