Form parts
It also possible to use form parts separately, without the form wrapper. In
this case, you need to include CSRF token manually if the form method is
POST.
{%- call ui.util.call(show_example) -%}
{%- raw %}
{{ ui.form_start(method="POST") }}
{{ h.csrf_input() }}
{%- call ui.util.call(ui.form_actions) -%}
{{ ui.button("Submit", type="submit") }}
{%- endcall %}
{{ ui.form_end() }}
{%- endraw %}
{%- endcall %}
