just reading through you install guide at http://www.grocerycrud.com/documentation/how-to-install-a-new-theme
It doesn't tell you what file/s need to be modified with the example code
public function bootstrap_theme()
{
$crud = new grocery_CRUD();
$crud->set_theme('bootstrap');
$crud->set_subject('Customer', 'Customers');
$crud->set_table('customers');
$crud->columns('customerName','contactLastName','phone','city',
'country','salesRepEmployeeNumber','creditLimit');
$crud->display_as('salesRepEmployeeNumber','from Employeer')
->display_as('customerName','Name')
->display_as('contactLastName','Last Name');
$crud->set_relation('salesRepEmployeeNumber','employees','lastName');
$output = $crud->render();
}
