function JsExampleController::getJsAccordionImplementation

Accordion page implementation.

We're allowing a twig template to define our content in this case, which isn't normally how things work, but it's easier to demonstrate the JavaScript this way.

Return value

array A renderable array.

    // practice, but which allows us to demonstrate adding JavaScript here.
    $build['myelement'] = [
        '#theme' => 'js_example_accordion',
        '#title' => $title,
    ];
    // Add our script. It is tiny, but this demonstrates how to add it. We pass
    // our module name followed by the internal library name declared in
    // libraries yml file.
    $build['myelement']['#attached']['library'][] = 'js_example/js_example.accordion';
    // Return the renderable array.
