We already customized the template used for every field whose data type is id. But you can also go deeper, and customize the way that just one specific field is rendered.

For example, let's say we need to customize how the "full name" field is rendered. No problem: in config.yml, find User, list, fields, and change fullName to the expanded configuration. To control the template add... surprise! A template option set to, how about, _field_user_full_name.html.twig:

... lines 1 - 80
... lines 82 - 91
... lines 93 - 117

Copy that name. It expects this to live in the standard easy_admin directory. Create it there!

Since this is a template for one field, it will have access to the User object as an item variable. And that makes life easy. Add if item.isScientist - that's a property on User - then add a cool graduation cap:

{% if item.isScientist %}
<i class="fa fa-graduation-cap"></i>
{% endif %}
... lines 4 - 6

Below, print the full name. To do that, you can use a value variable. Pipe it through |default('Stranger'), just in case the user doesn't have any name data:

{% if item.isScientist %}
<i class="fa fa-graduation-cap"></i>
{% endif %}
{{ value|default('Stranger') }}

Try it! Yes! We now know how to customize entire page templates - like list.html.twig, templates for a specific field type, or the template for just one field.

Time to move into forms!
