3 hrs and solution is here.
user\plugins\form\templates\forms\default\data.html.twig
From:
{% for val in value %}
{% if val is iterable %}
<ul>
{% for v in val %}
<li>{{ string(v)|e }}</li>
{% endfor %}
</ul>
{% else %}
<li>{{ string(val)|e }}</li>
{% endif %}
{% endfor %}
Edit to this:
{% for val in value %}
{% if val is iterable %}
<ul>
{% for item in form.value(field.name) %}
<li><a href="**SITE_URL**{{ string(item.path) }}">{{ item.name }}</a></li>
{% endfor %}
</ul>
{% else %}
<li>{{ string(form.value(field.name))|nl2br }}</li>
{% endif %}
{% endfor %}
I find solution here: Contact form and file upload - display images in data.{html|text}.twig
But have a one other problem, the files show cicling whan you add more that one file.
I try to find solution for this.
