Issue description

https://community.contao.org/de/showthread.php?71581-Header-im-parentView

Steps to reproduce

1. create standalone MM (mm_parent)
2. create child MM (mm_child)
3. go to edit-mask of mm_child

Describe the behaviour of the application

There seems to be no configuration options for headerFields it just display's "Änderungsdatum" (tstamp) which is not even an explicit attribute of mm_parent.

Describe the expected behaviour of the application

There should either be a config option (not shure if attributes, input-mask or rendersettings is the right place) or the headerFields should be determined by convention (like allways use id, title, name, headline, tstamp... if present)

I would not display anything else at this point - it would be important to display the breadcrumb in the header area! #586

maybe something like this would be great #178

and that the icon pen leads to the input mask of the parent MMs

[zonky2]

During the discussion we agreed that it does not need the additional information in the header.

However, we are examining the implementation of a clickable breadcrumb.

@stefanheimes pls check your POC

Just wanted to mention that before i updated (it was alpha17 i guess) i did have propper headerfields.

You can build an own event listener with BuildDataDefinitionEvent https://github.com/contao-community-alliance/dc-general/blob/master/src/ContaoCommunityAlliance/DcGeneral/Factory/Event/BuildDataDefinitionEvent.php and add your properties

...
$backendView = $container->getDefinition(Contao2BackendViewDefinitionInterface::NAME);

$listingConfig = $backendView->getListingConfig();

$listingConfig->setHeaderPropertyNames(['tstamp', 'name', 'description']);

Edit...

better Event: GetParentHeaderEvent https://github.com/contao-community-alliance/dc-general/blob/d7a265e203f29d9637c20681696b4554cc288829/src/ContaoCommunityAlliance/DcGeneral/Contao/View/Contao2BackendView/Event/GetParentHeaderEvent.php

(thx @baumannsven)

@zonky2 We should split the breadcrumb issue into a separate feature request for 2.2 and assign to @stefanheimes.
