@jongotlin how would you like to see that form rendered? Could you share a screenshot of some quick mockup proposal? Thanks!

The form should render like this imo

These are the form types used

// FooType
$builder
    ->add('test', TextType::class)
    ->add('foo', BarType::class)
;

// BarType
$builder->add('child', TextType::class);

It can be solved by changing bootstrap_3_horizontal_layout.html.twig to

{% block form_row -%}
+    {% if form.children|length == 0 %}
        <div class="form-group{% if (not compound or force_error|default(false)) and not valid %} has-error{% endif %}">
            {{- form_label(form) -}}
            <div class="{{ block('form_group_class') }}">
+    {% endif %}
    {{- form_widget(form) -}}
    {{- form_errors(form) -}}
+    {% if form.children|length == 0 %}
            </div>
        </div>
+    {% endif %}
{%- endblock form_row %}

But I' not sure what side effects that will cause...

For a compound class, the choice is up to the dev just use:

$builder->add('foo', SomeCompoundType::class, array('label' => false));

For handling the label and the block with no child, there is a work in progress (maybe for 3.2 :), see #17609.

@HeahDude, that's not the case when using the horizontal theme. The Bootstrap divs are rendered even though the label isn't. See

So this is a nice improvement! 👍

Wouldn't that change better fit by overriding form_rows block instead ? maybe it could use only one if ?

Or maybe the fix should just to be a new line after the parent label ?
In that way using false just makes the line disappear.
Why this label would not be printed ? It would not be consistent with other templates.
What do you think ?

Overriding form_rows wont fix it if using form_row(form.foo) directly from the template.
Yes, maybe the extra column should be removed only if label is false. I'll open a pr for it.

Thank you for this issue.
There has not been a lot of activity here for a while. Has this been resolved?

Just a quick reminder to make a comment on this. If I don't hear anything I'll close this.

Hey,

I didn't hear anything so I'm going to close it. Feel free to comment if this is still relevant, I can always reopen!
