+# Form Triggers
+
+**Form Triggers** in FlutterFlow allow you to respond dynamically to user input on widgets like dropdowns, sliders, toggles, and text fields. Whether it’s selecting an option, toggling a switch, or typing in a field, these triggers help you create interactive, responsive experiences by executing actions based on user interaction.
+
+## On Selected
+
+The **On Selected** action trigger is used to perform actions when a user selects or changes a value from a widget that presents multiple options. This trigger is associated with form widgets where selection input is required, such as [Dropdown](form-widgets/dropdown.md), [RadioButton](form-widgets/radiobutton.md), [CheckboxGroup](form-widgets/checkbox.md#checkboxgroup), [ChoiceChips](form-widgets/choicechips.md), and [Slider](../../../ui/widgets/built-in-widgets/slider.md).
+
+:::tip[Possible use cases]
+
+- **Dropdown – Shipping Method Selection:** User selects a shipping method from options like "Standard", "Express", or "Next Day". Action under the *On Selected* trigger sets the app state variable `shippingOption`, which updates pricing or estimated delivery time dynamically.
+- **Slider – Show Volume Level in Snackbar:** User adjusts a Slider from 0 to 100. The *On Selected* trigger displays a Snackbar showing the current volume: Volume set to: [sliderValue].
+- **ChoiceChips – Filter Products by Category:** User taps a chip like "All", "Electronics", or "Clothing". The *On Selected* trigger might set an app state variable (e.g., `selectedCategory`) and update the product list to match the chosen category.
+
+:::
+
+To use the **On Selected** trigger:
+
+1. Start by selecting a supported widget, such as a Dropdown.
+2. Open the **Actions** tab in the properties panel and click **+ Add Action**.
+3. You will notice that the **Type of Action** (aka callback) is already set to **On Selected**. That means actions added under this will be called whenever the selection changes.
+4. Finally, define the actions you want to perform when the user makes a selection, such as setting a variable, navigating to another page, or displaying a message.
+
+![on-selected](imgs/on-selected.avif)
+
+## On Toggled On / On Toggled Off
+
+The **On Toggled On** and **On Toggled Off** action triggers are used to perform actions when a user turns a toggleable widget on or off. These triggers are supported by widgets such as [Checkbox](form-widgets/checkbox.md), [CheckboxListTile](form-widgets/checkbox.md#checkboxlisttile), [Switch](form-widgets/switch.md), and [SwitchListTile](form-widgets/switch.md#switchlisttile), any widget that represents a binary state.
+
+These triggers are especially useful when you want to conditionally execute different actions based on whether a user enables or disables a setting, preference, or feature.
+
+:::tip[Possible use cases]
+
+- **Switch – Enable Dark Mode:** User toggles a Switch to enable Dark Mode. Action under the *On Toggled On* trigger sets the dark mode.
+- **Checkbox – Agree to Terms:** User checks a Checkbox labeled “I agree to the terms and conditions.” The *On Toggled On* trigger enables the Submit button. If the user unchecks it, the *On Toggled Off* trigger disables the button again.
+- **CheckboxListTile – Select Notification Channels:** User checks or unchecks options like Email, SMS, or Push Notifications. Each toggle fires either *On Toggled O*n or *On Toggled Off* to update selected preferences in the backend.
+
+:::
+
+To use the **On Toggled On** or **On Toggled Off** trigger:
+
+1. Start by selecting a supported widget, such as a Switch.
+2. Open the **Actions** tab in the properties panel and click **+ Add Action**.
+3. Choose **On Toggled On** to define actions when the toggle is switched on, or **On Toggled Off** to define actions when it's switched off.
+4. Add your desired actions, such as updating a variable, showing a message, enabling a button, or triggering a backend call.
+
+![on-toggle](imgs/on-toggle.avif)
+
+## On Change
+
+The **On Change** action trigger is used to respond to real-time user input as they type or modify the contents of an input field. This trigger is supported by widgets such as [TextField](form-widgets/text-field.md) and [Pincode](../../../ui/widgets/built-in-widgets/pincode.md).
+
+It’s ideal for enabling live form validations, updating app state as the user types, or enabling/disabling UI elements based on the current input.
+
+:::tip[Possible use cases]
+
+- **TextField – Enable Button When Email Is Entered:** As the user types in an email TextField, action under the *On Change* trigger checks if the input is a valid email. If it is, it enables the Continue button.
+- **Pincode – Auto Submit When Complete:** When a user finishes entering a 6-digit code in a Pincode widget, action under the *On Change* trigger checks if the full code is entered and triggers form submission or a backend call.
+
+:::
+
+To use the **On Change** trigger:
+
+1. Start by selecting a supported widget, such as a TextField.
+2. Open the **Actions** tab in the properties panel and click **+ Add Action**.
+3. Choose **On Change** from the list of available triggers.
+4. Define the actions to trigger, such as setting a variable, showing a message, or calling an API.
+
+![on-change](imgs/on-change.avif)
+
+---
+
+## On Focus Change
+
+The **On Focus Change** trigger fires whenever an input field gains or loses focus, like when a user taps into or out of a [TextField](form-widgets/text-field.md) and [Pincode](../../../ui/widgets/built-in-widgets/pincode.md) widget. It’s useful for providing user guidance (on focus) or performing validations.
+
+:::tip[Possible use cases]
+
+- **TextField – Show Hint on Focus:** When the TextField gains focus, action under the *On Focus Change* trigger displays a helper text or tooltip with input instructions (e.g., “Enter your phone number without dashes”).
+- **Pincode – Validate on Exit:** When the user finishes entering the code and the Pincode widget loses focus, action under the *On Focus Change* trigger runs validation logic to check if the input is complete or valid, and displays an error if it's not.
+
+:::
+
+To use the **On Focus Change** trigger:
+
+1. Start by selecting a supported widget, such as a TextField.
+2. Open the **Actions** tab in the properties panel and click **+ Add Action**.
+3. Choose **On Focus Change** from the list of available triggers.
+4. Define the actions to trigger, such as showing helper text, validating input, or updating the UI based on focus.
