useModalForm

useModalForm hook also allows you to manage a form inside a modal component. It provides some useful methods to handle the form modal.

info

useModalForm hook is extended from useForm hook from the @refinedev/mantine package. This means that you can use all the features of useForm hook.

Basic Usage​

We'll show three examples, "create", "edit" and "clone". Let's see how useModalForm is used in all.

In this example, we will show you how to "create" a record with useModalForm.

http://localhost:3000/posts
import React from "react";
import { useTable } from "@refinedev/react-table";
import { ColumnDef, flexRender } from "@tanstack/react-table";
import { GetManyResponse, useMany } from "@refinedev/core";
import { List, useModalForm, SaveButton } from "@refinedev/mantine";
import {
Box,
Group,
ScrollArea,
Table,
Pagination,
Modal,
Select,
TextInput,
} from "@mantine/core";

const PostList: React.FC = () => {
const {
getInputProps,
saveButtonProps,
modal: { show, close, title, visible },
} = useModalForm({
refineCoreProps: { action: "create" },
initialValues: {
title: "",
status: "",
content: "",
},
validate: {
title: (value) => (value.length < 2 ? "Too short title" : null),
status: (value) =>
value.length <= 0 ? "Status is required" : null,
},
});

const columns = React.useMemo<ColumnDef<IPost>[]>(
() => [
{
id: "id",
header: "ID",
accessorKey: "id",
},
{
id: "title",
header: "Title",
accessorKey: "title",
meta: {
filterOperator: "contains",
},
},
{
id: "status",
header: "Status",
accessorKey: "status",
meta: {
filterElement: function render(props: FilterElementProps) {
return (
<Select
defaultValue="published"
data={[
{ label: "Published", value: "published" },
{ label: "Draft", value: "draft" },
{ label: "Rejected", value: "rejected" },
]}
{...props}
/>
);
},
filterOperator: "eq",
},
},
],
[],
);

const {
getHeaderGroups,
getRowModel,
setOptions,
refineCore: {
setCurrent,
pageCount,
current,
tableQueryResult: { data: tableData },
},
} = useTable({
columns,
});

return (
<>
<Modal opened={visible} onClose={close} title={title}>
<TextInput
mt={8}
label="Title"
placeholder="Title"
{...getInputProps("title")}
/>
<Select

placeholder="Pick one"
data={[
{ label: "Published", value: "published" },
{ label: "Draft", value: "draft" },
{ label: "Rejected", value: "rejected" },
]}
{...getInputProps("status")}
/>
<Box
mt={8}
sx={{ display: "flex", justifyContent: "flex-end" }}
>
<SaveButton {...saveButtonProps} />
</Box>
</Modal>
<ScrollArea>
<List createButtonProps={{ onClick: () => show() }}>
<Table highlightOnHover>
<thead>
{getHeaderGroups().map((headerGroup) => (
<tr key={headerGroup.id}>
{headerGroup.headers.map((header) => {
return (
<th key={header.id}>
{!header.isPlaceholder && (
<Group spacing="xs" noWrap>
<Box>
{flexRender(
header.column
.columnDef
.header,
header.getContext(),
)}
</Box>
</Group>
)}
</th>
);
})}
</tr>
))}
</thead>
<tbody>
{getRowModel().rows.map((row) => {
return (
<tr key={row.id}>
{row.getVisibleCells().map((cell) => {
return (
<td key={cell.id}>
{flexRender(
cell.column.columnDef
.cell,
cell.getContext(),
)}
</td>
);
})}
</tr>
);
})}
</tbody>
</Table>
<br />
<Pagination
position="right"
total={pageCount}
page={current}
onChange={setCurrent}
/>
</List>
</ScrollArea>
</>
);
};

interface IPost {
id: number;
title: string;
status: "published" | "draft" | "rejected";
}

Properties​

refineCoreProps​

All useForm properties also available in useStepsForm. You can find descriptions on useForm docs.

const modalForm = useModalForm({
refineCoreProps: {
action: "edit",
resource: "posts",
id: "1",
},
});

initialValues​

Only available in "create" form.

Default values for the form. Use this to pre-populate the form with data that needs to be displayed.

const modalForm = useModalForm({
initialValues: {
title: "Hello World",
},
});

defaultVisible​

Default: false

When true, modal will be visible by default.

const modalForm = useModalForm({
modalProps: {
defaultVisible: true,
},
});

autoSubmitClose​

Default: true

When true, modal will be closed after successful submit.

const modalForm = useModalForm({
modalProps: {
autoSubmitClose: false,
},
});

autoResetForm​

Default: true

When true, form will be reset after successful submit.

const modalForm = useModalForm({
modalProps: {
autoResetForm: false,
},
});

syncWithLocation​

Default: false

When true, the modals visibility state and the id of the record will be synced with the URL.

This property can also be set as an object { key: string; syncId?: boolean } to customize the key of the URL query parameter. id will be synced with the URL only if syncId is true.

const modalForm = useModalForm({
syncWithLocation: { key: "my-modal", syncId: true },
});

Return Values​

tip

All useForm return values also available in useModalForm. You can find descriptions on useForm docs.

All mantine useForm return values also available in useModalForm. You can find descriptions on mantine docs.

visible​

Current visibility state of the modal.

const modalForm = useModalForm({
defaultVisible: true,
});

console.log(modalForm.modal.visible); // true

title​

Title of the modal. Based on resource and action values

const {
modal: { title },
} = useModalForm({
refineCoreProps: {
resource: "posts",
action: "create",
},
});

console.log(title); // "Create Post"

close​

A function that can close the modal. It's useful when you want to close the modal manually.

const {
getInputProps,
modal: { close, visible, title },
} = useModalForm();

return (
<Modal opened={visible} onClose={close} title={title}>
<TextInput
mt={8}
label="Title"
placeholder="Title"
{...getInputProps("title")}
/>
<Box mt={8} sx={{ display: "flex", justifyContent: "flex-end" }}>
<SaveButton {...saveButtonProps} />
<Button onClick={close}>Cancel</Button>
</Box>
</Modal>
);

submit​

A function that can submit the form. It's useful when you want to submit the form manually.

const {
modal: { submit },
} = useModalForm();

// ---

return (
<Modal opened={visible} onClose={close} title={title}>
<TextInput
mt={8}
label="Title"
placeholder="Title"
{...getInputProps("title")}
/>
<Box mt={8} sx={{ display: "flex", justifyContent: "flex-end" }}>
<Button onClick={submit}>Save</Button>
</Box>
</Modal>
);

show​

A function that can show the modal.

const {
getInputProps,
modal: { close, visible, title, show },
} = useModalForm();

const onFinishHandler = (values) => {
onFinish(values);
show();
};

return (
<>
<Button onClick={}>Show Modal</Button>
<Modal opened={visible} onClose={close} title={title}>
<TextInput
mt={8}
label="Title"
placeholder="Title"
{...getInputProps("title")}
/>
<Box mt={8} sx={{ display: "flex", justifyContent: "flex-end" }}>
<SaveButton {...saveButtonProps} />
</Box>
</Modal>
</>
);

saveButtonProps​

It contains all the props needed by the "submit" button within the modal (disabled,loading etc.). You can manually pass these props to your custom button.

const { getInputProps, modal, saveButtonProps } = useModalForm();

return (
<Modal {...modal}>
<TextInput
mt={8}
label="Title"
placeholder="Title"
{...getInputProps("title")}
/>
<Box mt={8} sx={{ display: "flex", justifyContent: "flex-end" }}>
<Button
{...saveButtonProps}
onClick={(e) => {
// -- your custom logic
saveButtonProps.onClick(e);
}}
/>
</Box>
</Modal>
);

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.

pages/user/create.tsx
import React from "react";
import { useModalForm } from "@refinedev/mantine";
import { TextInput, Modal } from "@mantine/core";

const UserCreate: React.FC = () => {
const {
getInputProps,
saveButtonProps,
modal: { show, close, title, visible },
} = useModalForm({
refineCoreProps: { action: "create" },
initialValues: {
name: "",
surname: "",
},
transformValues: (values) => ({
fullName: `${values.name} ${values.surname}`,
}),
});

return (
<Modal opened={visible} onClose={close} title={title}>
<TextInput
mt={8}
label="Name"
placeholder="Name"
{...getInputProps("name")}
/>
<TextInput
mt={8}
label="Surname"
placeholder="Surname"
{...getInputProps("surname")}
/>
<Box mt={8} sx={{ display: "flex", justifyContent: "flex-end" }}>
<Button
{...saveButtonProps}
onClick={(e) => {
// -- your custom logic
saveButtonProps.onClick(e);
}}
/>
</Box>
</Drawer>
);
};
