I am trying to show my Bootstrap dropdown menu on t-on-keyup. 

When i try to call new bootstrap.Dropdown(element) is says that it's undefined.

If I'm correct, bootstrap is already inside the odoo system. So I don't have any imports for bootstrap in my application.

This is the function I am trying to call:

showDropdown = (dropdownElement) => {
    if (dropdownElement) {
	​	​const dropdown = new bootstrap.Dropdown(dropdownElement);
	​	​dropdown.show();
    }
}

Do I still need to import bootstrap individually? Or am I doing something else wrong?
