Answer 1

You can create a custom template for the PostAttributes :

Example:

/* ShowMapper in admin */
$showMapper->add('attributes', null, array(
    'template' => 'YOUR_TEMPLATE.html.twig' // <-- This is the trick
));

In your template, you can extend the base show field ( SonataAdminBundle:CRUD:base_show_field.html.twig or @SonataAdmin/CRUD/base_show_field.html.twig for symfony > 4.0), and override the field block. The variable named value stores the data in twig.

Example:

YOUR_TEMPLATE.html.twig

{% extends 'SonataAdminBundle:CRUD:base_show_field.html.twig' %}
{# for sf > 4.0 #}
{#  {% extends '@SonataAdmin/CRUD/base_show_field.html.twig' %} #}

{% block field %}
    {% for val in value %}
        {{ val.name }} - {{ val.value }} {# I'm just guessing the object properties #}
        <br/>
    {% endfor %}
{% endblock %}

@SlimenTN you can try changing this line in template file:

{% extends 'SonataAdminBundle:CRUD:base_show_field.html.twig' %}

with this:

{% extends '@SonataAdmin/CRUD/base_show_field.html.twig' %}

The rest of code seems ok (I have the same in a SF4 project)
