I am trying to submit a form and then display data using my controller in a Twig template.
I want to do How to show a string once you submit a form in a page reloading the page? something like this, just instead of showing string, I want to show a table created using Twig.
Something like this:
return ( '#theme' => 'my_template', '#var_1' => $this->t("var 1"), );
Fews things to keep in mind, that I want to display on the same page, so the method using Form API will be much appreciated.
