admin on rest hide resource component in sidebar

I need a resource with all its configuration, but I don't want it to be showed in sidebar

As explained in the documentation, you can provide your Menu component to the Admin component using it's menu prop. See https://marmelab.com/react-admin/Admin.html#menu

Please note that this prop will be deprecated soon in favor of appLayout but you'll still use this custom menu in your custom layout anyway.

// in src/Menu.js
import React from 'react';
import { connect } from 'react-redux';
import { MenuItemLink, getResources } from 'react-admin';
import { withRouter } from 'react-router-dom';
import Responsive from '../layout/Responsive';

const Menu = ({ resources, onMenuClick, logout }) => (
    <div>
        {resources
            .filter(resource => resource.name !== 'excluded-resource')
            .map(resource => (
                <MenuItemLink to={`/${resource.name}`} primaryText={resource.name} onClick={onMenuClick} />
            ))
        }
        <Responsive
            small={logout}
            medium={null} // Pass null to render nothing on larger devices
        />
    </div>
);

const mapStateToProps = state => ({
    // Rerieve all known resources
    resources: getResources(state),
});

export default withRouter(connect(mapStateToProps)(Menu));
