useStepsForm
useStepsForm allows you to manage a form with multiple steps. It provides features such as which step is currently active, the ability to go to a specific step and validation when changing steps etc.
useStepsForm hook is extended from useForm from the @refinedev/mantine package. This means that you can use all the functionalities of useForm in your useStepsForm.
Basic Usage
We'll show two examples, one for creating and one for editing a post. Let's see how useStepsForm is used in both.
- create
- edit
Here is the final result of the form: We will explain the code in following sections.
Here is the final result of the form: We will explain the code in following sections.
In this example we're going to build a Post "create" form. To creating a multi-step form, we will use <Stepper/> component from Mantine. To handle the state of both the form and the steps, we will use useStepsForm hook.
To show your form inputs step by step, first import and use useStepsForm hook in your page:
import React from "react";
import { HttpError } from "@refinedev/core";
import { Create } from "@refinedev/mantine";
type FormValues = Omit<IPost, "id">;
const PostCreatePage: React.FC = () => {
const {
saveButtonProps,
getInputProps,
values,
steps: { currentStep, gotoStep },
} = useStepsForm<IPost, HttpError, FormValues>({
initialValues: {
title: "",
status: "",
slug: "",
content: "",
},
validate: (values) => {
if (currentStep === 0) {
return {
title: values.title ? null : "Title is required",
slug: values.slug ? null : "Slug is required",
};
}
if (currentStep === 1) {
return {
status: values.status ? null : "Status is required",
};
}
return {};
},
});
return <Create>create page</Create>;
};
useStepsForm is generic over the type form data to help you type check your code.
This hook returns a set of useful values to render <Stepper/>. Given current value, you should have a way to render your form items conditionally with this index value.
Here, we're going to use a <Stepper/> component to render the form items based on the currentStep and we added <Button> to footer with gotoStep function to navigate between steps.
import React from "react";
import { HttpError } from "@refinedev/core";
import { Create } from "@refinedev/mantine";
type FormValues = Omit<IPost, "id">;
const PostCreatePage: React.FC = () => {
const {
saveButtonProps,
getInputProps,
values,
steps: { currentStep, gotoStep },
} = useStepsForm<IPost, HttpError, FormValues>({
initialValues: {
title: "",
status: "",
slug: "",
content: "",
},
validate: (values) => {
if (currentStep === 0) {
return {
title: values.title ? null : "Title is required",
slug: values.slug ? null : "Slug is required",
};
}
if (currentStep === 1) {
return {
status: values.status ? null : "Status is required",
};
}
return {};
},
});
return (
<Create
footerButtons={
<Group position="right" mt="xl">
{currentStep !== 0 && (
<Button
variant="default"
onClick={() => gotoStep(currentStep - 1)}
>
Back
</Button>
)}
{currentStep !== 3 && (
<Button onClick={() => gotoStep(currentStep + 1)}>
Next step
</Button>
)}
{currentStep === 2 && <SaveButton {...saveButtonProps} />}
</Group>
}
>
<Stepper
active={currentStep}
onStepClick={gotoStep}

<Stepper.Step

</Stepper>
</Create>
);
};
Properties
refineCoreProps
All useForm properties also available in useStepsForm. You can find descriptions on useForm docs.
const stepsForm = useStepsForm({
refineCoreProps: {
action: "edit",
resource: "posts",
id: "1",
},
});
stepsProps
defaultStep
Default:
0
Sets the default starting step number. Counting starts from 0.
const stepsForm = useStepsForm({
stepsProps: {
defaultStep: 0,
},
});
isBackValidate
Default:
false
When is true, validates a form fields when the user navigates to a previous step.
const stepsForm = useStepsForm({
stepsProps: {
isBackValidate: true,
},
});
overtimeOptions
If you want loading overtime for the request, you can pass the overtimeOptions prop to the this hook. It is useful when you want to show a loading indicator when the request takes too long.
interval is the time interval in milliseconds. onInterval is the function that will be called on each interval.
Return overtime object from this hook. elapsedTime is the elapsed time in milliseconds. It becomes undefined when the request is completed.
const { overtime } = useStepsForm({
//...
overtimeOptions: {
interval: 1000,
onInterval(elapsedInterval) {
console.log(elapsedInterval);
},
}
});
console.log(overtime.elapsedTime); // undefined, 1000, 2000, 3000 4000, ...
// You can use it like this:
{elapsedTime >= 4000 && <div>this takes a bit longer than expected</div>}
autoSave
If you want to save the form automatically after some delay when user edits the form, you can pass true to autoSave.enabled prop.
It also supports onMutationSuccess and onMutationError callback functions. You can use isAutoSave parameter to determine whether the mutation is triggered by autoSave or not.
Works only in action: "edit" mode.
onMutationSuccess and onMutationError callbacks will be called after the mutation is successful or failed.
enabled
To enable the autoSave feature, set the enabled parameter to true.
useStepsForm({
refineCoreProps: {
autoSave: {
enabled: true,
},
}
})
debounce
Set the debounce time for the autoSave prop. Default value is 1000.
useStepsForm({
refineCoreProps: {
autoSave: {
enabled: true,
debounce: 2000,
},
}
})
Return Values
steps
The props needed by the <Stepper> component.
currenStep
Current step, counting from 0.
gotoStep
Is a function that allows you to programmatically change the current step of a form. It takes in one argument, step, which is a number representing the index of the step you want to navigate to.
overtime
overtime object is returned from this hook. elapsedTime is the elapsed time in milliseconds. It becomes undefined when the request is completed.
const { overtime } = useStepsForm();
console.log(overtime.elapsedTime); // undefined, 1000, 2000, 3000 4000, ...
autoSaveProps
If autoSave is enabled, this hook returns autoSaveProps object with data, error, and status properties from mutation.
FAQ
How can I change the form data before submitting it to the API?
You may need to modify the form data before it is sent to the API.
For example, Let's send the values we received from the user in two separate inputs, name and surname, to the API as fullName.
import React from "react";
import { useStepsForm } from "@refinedev/mantine";
const UserCreate: React.FC = () => {
const {
saveButtonProps,
getInputProps,
values,
steps: { currentStep, gotoStep },
} = useStepsForm({
refineCoreProps: { action: "create" },
initialValues: {
name: "",
surname: "",
},
transformValues: (values) => ({
fullName: `${values.name} ${values.surname}`,
}),
});
// ...
};
