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/react-hook-form
package. This means you can use all the features of useForm
.
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. We also added a relational category field to expand our example.
To split your <input/>
components under a <form/>
component, first import and use useStepsForm
hook in your page:
import { HttpError } from "@refinedev/core";
import { useStepsForm } from "@refinedev/react-hook-form";
const PostCreate = () => {
const {
refineCore: { onFinish, formLoading },
register,
handleSubmit,
formState: { errors },
steps: { currentStep, gotoStep },
} = useStepsForm<IPost, HttpError, IPost>();
return <div>...</div>;
};
interface ICategory {
id: number;
title: string;
}
interface IPost {
id: number;
title: string;
content: string;
status: "published" | "draft" | "rejected";
category: {
id: ICategory["id"];
};
}
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 steps form. 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 switch
statement to render the form items based on the currentStep
.
import { HttpError, useSelect } from "@refinedev/core";
import { useStepsForm } from "@refinedev/react-hook-form";
const PostCreate = () => {
const {
refineCore: { onFinish, formLoading },
register,
handleSubmit,
formState: { errors },
steps: { currentStep, gotoStep },
} = useStepsForm<IPost, HttpError, IPost>();
const { options } = useSelect<ICategory, HttpError>({
resource: "categories",
});
const renderFormByStep = (step: number) => {
switch (step) {
case 0:
return (
<>
<label>Title: </label>
<input
{...register("title", {
required: "This field is required",
})}
/>
{errors.title && <span>{errors.title.message}</span>}
</>
);
case 1:
return (
<>
<label>Status: </label>
<select {...register("status")}>
<option value="published">published</option>
<option value="draft">draft</option>
<option value="rejected">rejected</option>
</select>
</>
);
case 2:
return (
<>
<label>Category: </label>
<select
{...register("category.id", {
required: "This field is required",
})}
>
{options?.map((category) => (
<option
key={category.value}
value={category.value}
>
{category.label}
</option>
))}
</select>
{errors.category && (
<span>{errors.category.message}</span>
)}
<br />
<br />
<label>Content: </label>
<textarea
{...register("content", {
required: "This field is required",
})}
rows={10}
cols={50}
/>
{errors.content && (
<span>{errors.content.message}</span>
)}
</>
);
}
};
return <div>...</div>;
};
interface ICategory {
id: number;
title: string;
}
interface IPost {
id: number;
title: string;
content: string;
status: "published" | "draft" | "rejected";
category: {
id: ICategory["id"];
};
}
Since category
is a relational data, we use useSelect
to fetch its data.
Now, we can use renderFormByStep
function to render the form items based on the currentStep
and gotoStep
function to navigate between steps.
import { HttpError, useSelect } from "@refinedev/core";
import { useStepsForm } from "@refinedev/react-hook-form";
const PostCreate = () => {
const {
refineCore: { onFinish, formLoading },
register,
handleSubmit,
formState: { errors },
steps: { currentStep, gotoStep },
} = useStepsForm<IPost, HttpError, IPost>();
const { options } = useSelect<ICategory, HttpError>({
resource: "categories",
});
const renderFormByStep = (step: number) => {
switch (step) {
case 0:
return (
<>
<label>Title: </label>
<input
{...register("title", {
required: "This field is required",
})}
/>
{errors.title && <span>{errors.title.message}</span>}
</>
);
case 1:
return (
<>
<label>Status: </label>
<select {...register("status")}>
<option value="published">published</option>
<option value="draft">draft</option>
<option value="rejected">rejected</option>
</select>
</>
);
case 2:
return (
<>
<label>Category: </label>
<select
{...register("category.id", {
required: "This field is required",
})}
>
{options?.map((category) => (
<option
key={category.value}
value={category.value}
>
{category.label}
</option>
))}
</select>
{errors.category && (
<span>{errors.category.message}</span>
)}
<br />
<br />
<label>Content: </label>
<textarea
{...register("content", {
required: "This field is required",
})}
rows={10}
cols={50}
/>
{errors.content && (
<span>{errors.content.message}</span>
)}
</>
);
}
};
if (formLoading) {
return <div>Loading...</div>;
}
return (
<div style={{ display: "flex", flexDirection: "column", gap: 16 }}>
<div style={{ display: "flex", gap: 36 }}>
{stepTitles.map((title, index) => (
<button
key={index}
onClick={() => gotoStep(index)}
style={{
backgroundColor:
currentStep === index ? "lightgray" : "initial",
}}
>
{index + 1} - {title}
</button>
))}
</div>
<form autoComplete="off">{renderFormByStep(currentStep)}</form>
<div style={{ display: "flex", gap: 8 }}>
{currentStep > 0 && (
<button
onClick={() => {
gotoStep(currentStep - 1);
}}
>
Previous
</button>
)}
{currentStep < stepTitles.length - 1 && (
<button
onClick={() => {
gotoStep(currentStep + 1);
}}
>
Next
</button>
)}
{currentStep === stepTitles.length - 1 && (
<button onClick={handleSubmit(onFinish)}>Save</button>
)}
</div>
</div>
);
};

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
The props needed by the manage state steps.
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,
},
});
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.
By default the autoSave
feature does not invalidate queries. However, you can use the invalidateOnUnmount
prop to invalidate queries upon unmount.
It also supports onMutationSuccess
and onMutationError
callback functions. You can use isAutoSave
parameter to determine whether the mutation is triggered by autoSave
or not.
autoSave
feature operates exclusively in edit
mode. Users can take advantage of this feature while editing data, as changes are automatically saved in editing mode. However, when creating new data, manual saving is still required.
onMutationSuccess
and onMutationError
callbacks will be called after the mutation is successful or failed.
enabled
Default:
false
To enable the autoSave
feature, set the enabled
parameter to true
.
useStepsForm({
refineCoreProps: {
autoSave: {
enabled: true,
},
},
});
debounce
Default:
1000
Set the debounce time for the autoSave
prop.
useStepsForm({
refineCoreProps: {
autoSave: {
enabled: true,
debounce: 2000,
},
},
});
onFinish
If you want to modify the data before sending it to the server, you can use onFinish
callback function.
useStepsForm({
refineCoreProps: {
autoSave: {
enabled: true,
onFinish: (values) => {
return {
foo: "bar",
...values,
};
},
},
},
});
invalidateOnUnmount
Default:
false
This prop is useful when you want to invalidate the list
, many
and detail
queries from the current resource when the hook is unmounted. By default, it invalidates the list
, many
and detail
queries associated with the current resource. Also, You can use the invalidates
prop to select which queries to invalidate.
useStepsForm({
refineCoreProps: {
autoSave: {
enabled: true,
invalidateOnUnmount: true,
},
},
});
Return Values
steps
The return values needed by the manage state steps.
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.
