create a searchable dropdown checklist in react

I have a JSON

let users = {
    activeUsers: [
        {
            userId: '1',
            email: '[email protected]',
            givenName: 'Marc',
            familyName: 'S-t',
        },
        {
            userId: '2',
            email: '[email protected]',
            givenName: 'Marc',
            familyName: 'S-t',
        },
        {
            userId: '3',
            email: '[email protected]',
            givenName: '',
            familyName: 'B-n',
        },
        {
            userId: '4',
            email: '[email protected]',
            givenName: 'Jeroen',
            familyName: 'V-k',
           
        },
        {
            userId: '5',
            email: '[email protected]',
            givenName: 'Dastan',
            familyName: 'H-d',
           
        },
        {
            userId: '6',
            email: '[email protected]',
            givenName: 'Emin',
            familyName: 'D-v',
         
        },
        {
            userId: '7',
            email: '[email protected]',
            givenName: 'Douwe',
            familyName: 'H-a',
           
        },
    ],
};

need to make a dropdown with the above fields i have done this

    const renderlists = () => {
        return (
            <div>
                            <div>
                             <CheckboxDefault
                                    label={'select all'}  // this button to select and unselect all
                                    onChange={(event) => handleselectAll(event.target.checked)}
                             />
                            </div>
                            <div>
                                <p> Selected Contacts({userCount}) </p>
                            </div>
                  

                <div>
                    <div>
                        <InputSearch
                            placeholder={'search user'} // for searching user form list
                            onChange={(event) => handleSearch(event.target.value)}
                        />
                    </div>
                </div>
                <div>
                    {renderUsers(usersToShow, true)} //method to show user after search
                </div>
            </div>
        );
    };

i am not able to achieve the select all functionality when the user search and when the user do not search and uses the select and unselect all

when a user check select all, all the seven user should be selected and on unselecting any one of then the select all checkbox should be unchecked,
second when a user search the user the search result should come if all of them are selected the select all should be checked otherwise will work same that on selecting select all on the search result item it should select and unselect them but not the others which are not there in the search list, on selection the userid should be pushed into an array for hose users which are selected.
