* docs(react-form): add Chakra UI integration guide to ui-libraries documentation

Add comprehensive Chakra UI integration examples to the UI libraries guide,
covering both composable (Checkbox.Root) and pre-composed Checkbox components.
Includes code examples demonstrating how to integrate Chakra UI's Input and
Checkbox components with TanStack Form's Field component, maintaining
consistency with existing Mantine, Material UI, and shadcn/ui examples.

 ## Usage of TanStack Form with UI Libraries
 
-TanStack Form is a headless library, offering you complete flexibility to style it as you see fit. It's compatible with a wide range of UI libraries, including `Tailwind`, `Material UI`, `Mantine`, `shadcn/ui`, or even plain CSS.

 ### Prerequisites
 
 Before integrating TanStack Form with a UI library, ensure the necessary dependencies are installed in your project:
 
+- For `Chakra UI`, follow the installation instructions on their [official site](https://chakra-ui.com/docs/get-started/installation)
 - For `Material UI`, follow the installation instructions on their [official site](https://mui.com/material-ui/getting-started/).
 - For `Mantine`, refer to their [documentation](https://mantine.dev/).
 - For `shadcn/ui`, refer to their [official site](https://ui.shadcn.com/).

+### Usage with Chakra UI
+
+The process for integrating Chakra UI components is similar. Here's an example using Input and Checkbox from Chakra UI:
+
+```tsx
+<Field
+  name="name"
+  children={({ state, handleChange, handleBlur }) => (
+    <Input
+      value={state.value}
+      onChange={(e) => handleChange(e.target.value)}
+      onBlur={handleBlur}
+      placeholder="Enter your name"
+    />
+  )}
+/>
+<Field
+  name="isChecked"
+  children={({ state, handleChange, handleBlur }) => (
+    <Checkbox.Root
+      checked={state.value}
+      onCheckedChange={(details) => handleChange(!!details.checked)}
+      onBlur={handleBlur}
+    >
+      <Checkbox.HiddenInput />
+      <Checkbox.Control />
+      <Checkbox.Label>Accept terms</Checkbox.Label>
+    </Checkbox.Root>
+  )}
+/>
+```
+
+- The integration approach is the same as with Mantine, Material UI, and shadcn/ui.
+- Chakra UI exposes its Checkbox as a composable component with separate `Checkbox.Root`, `Checkbox.Control`, `Checkbox.Label`, and `Checkbox.HiddenInput` parts that you wire together.
+- The double negation `!!` is used on `onCheckedChange` to coerce Chakra's `"indeterminate"` state to a boolean, ensuring it matches the form state. See the [Chakra UI Checkbox documentation](https://chakra-ui.com/docs/components/checkbox#indeterminate) for more details.
+- Alternatively, Chakra UI offers a pre-composed Checkbox component that works the same way as their standard examples, without requiring manual composition. You can learn more about this closed component approach in the [Chakra UI Checkbox documentation](https://chakra-ui.com/docs/components/checkbox#closed-component).
+- The TanStack Form integration works identically with either approach—simply attach the `checked`, `onCheckedChange`, and `onBlur` handlers to your chosen component.
+
+Example using the closed Checkbox component:
+
+```tsx
+<Field
+  name="isChecked"
+  children={({ state, handleChange, handleBlur }) => (
+    <Checkbox
+      checked={state.value}
+      onCheckedChange={(details) => handleChange(!!details.checked)}
+      onBlur={handleBlur}
+    >
+      Accept terms
+    </Checkbox>
+  )}
+/>
+```
