<FilterDropdown>

Usage

<FilterDropdown> is a helper component for filter dropdowns in Ant Design <Table> components.

It serves as a bridge by synchronizing between its children's input value and <Table>'s filter values.

components/pages/postList.tsx
import {
List,
Table,
FilterDropdown,
Select,
useTable,
} from "@pankod/refine";

const PostList: React.FC = (props) => {
const { tableProps } = useTable<IPost>();

return (
<List>
<Table {...tableProps} rowKey="id">
<Table.Column dataIndex="id" title="ID" />
<Table.Column
dataIndex={["category", "id"]}
title="Category"
key="category.id"
filterDropdown={(props) => (
<FilterDropdown {...props}>
<Select
mode="multiple"
placeholder="Select Category"
options={[
{ label: "Ergonomic", value: "1" },
{ label: "Island", value: "2" },
]}
/>
</FilterDropdown>
)}
/>
</Table>
</List>
);
};

interface IPost {
id: string;
category: {
id: string;
}
}

Selecting categories from dropdown will send the id's of categories as filtering values to Table and data will be updated by refine under the hood.

<FilterDropdown> will put two buttons for filtering and clearing filter actions.

Show record action

tip

We added category options for <Select> manually for the sake of simplicity but useSelect hook can be used to populate the props of <Select>

const { selectProps: categorySelectProps } = useSelect<ICategory>({
resource: "categories",
optionLabel: "title",
optionValue: "id",
});

<Select {...categorySelectProps} />

Properties

selectedKeys, setSelectedKeys, confirm, clearFilters

These are to be passed from <Table.Column>'s filterDropdown prop.

mapValue

Determines the value passed to children. mapValue takes selectedKeys as an argument.

For example when using useSelect for <Select> component. In this case values must be mapped to numbers using mapValue.

import {
useTable,
Table,
FilterDropdown,
Select,
useSelect,
getDefaultFilter,
} from "@pankod/refine";

const { tableProps, filters } = useTable<IPost>({
initialFilter: [
{
field: "category.id",
value: [1, 2],
operator: "in",
},
],
});

const { selectProps: categorySelectProps } = useSelect<ICategory>({
resource: "categories",
optionLabel: "title",
optionValue: "id",
defaultValue: getDefaultFilter("category.id", filters, "in"),
});

<Table>
<Table.Column dataIndex="id" title="ID" />
<Table.Column
dataIndex={["category", "id"]}
title="Category"
key="category.id"
filterDropdown={(props) => (
<FilterDropdown
{...props}
mapValue={(selectedKeys) =>
selectedKeys.map((i) => parseInt(i.toString()))
}
>
<Select
style={{ minWidth: 200 }}
mode="multiple"
placeholder="Select Category"
{...categorySelectProps}
/>
</FilterDropdown>
)}
defaultFilteredValue={getDefaultFilter("category.id", filters, "in")}
/>
</Table>;
important

If syncWithLocation is enabled, on page refresh filter values will be type of string since they will be parsed from URL. This might produce some incompatibility if data for filter input comes from an API and it's not type of string.

getDefaultFilter finds filter values for a given column from the given filters. In the example, filters passed to getDefaultFilter includes filter values from the URL since it comes from useTable.
