I have an array of objects which has a structure like this

export const CardContents =[
    {
        id:1,
        brand:'Akko',
        product:'Product 1',
        img:Icon1,
        price:100,
        category:'Keycaps'
    },
    {
        id:11,
        brand:'Press Play',
        product:'Product 1',
        img:Icon1,
        price:100,
        category:'Keycaps'
        },
    {
        id:12,
        brand:'Zifriend',
        product:'Product 1',
        img:Icon1,
        price:100,
        category:'Keycaps'
        },
   {
        id:2,
        brand:'Ajazz',
        product:'Product 1',
        img:Icon2,
        price:100,
        category:'Switch'
    },

i want to make a sidebar for filtering my filtered array.
so i tried to filter my array by the category and sidebar filter function using this.

    const filteredData = CardContents.filter(CardContent => CardContent.category === 'Keycaps') 

    const [item, setItem] = useState(filteredData)

    const menuItems = [...new Set(filteredData.map((content) => content.brand))]

    const filterItems = (cat) => {
        const newItems = filteredData.filter((newcontent) => newcontent.brand === cat )
        setItem(newItems)
    }

this is my sidebar

function CategorySidebar({menuItems, filterItems, setItem}) {
  return (
    <div className="hidden md:flex md:basis-1/3 lg:basis-1/4 flex-col p-2 bg-white rounded-lg self-start sticky top-24">
    <h1 className='font-medium mb-2'>
        Brand
    </h1>
    <ul>
    {menuItems?.map((content) => (
        <li className='mb-1' onClick={() => filterItems(content)}>
            <label htmlFor={content.brand} className='flex items-center'>
                <input type="checkbox" className='mr-1' />
                {content}
            </label>
        </li>
    ))}
    </ul>
    <ul>
        <li onClick={() => setItem()}>
            <label htmlFor="" className='flex items-center'><input type="checkbox" className='mr-1' />See all</label>
        </li>
    </ul>
    </div>
  )
}

but the problem is when i click the category its not working

so how do i filtering my filtered array?
