Feature request: Preview for inline/IRRE elements

[di-development]

Preview for inline/IRRE elements
I'm not entirely sure whether this is a task for Mask or for TYPO3. Here is an excerpt from my TCA:
'content_elements' => [ 'exclude' => 0, 'label' => 'mylabel', 'config' => [ 'type' => 'inline', 'foreign_table' => 'tt_content', 'foreign_field' => 'tx_wissensthema', 'appearance' => [ 'collapseAll' => 1, 'levelLinksPosition' => 'top', 'showSynchronizationLink' => 1, 'showPossibleLocalizationRecords' => 1, 'showAllLocalizationLink' => 1, ], 'behaviour' => [ 'enableCascadingDelete' => true, ], ], ],
Do you have any idea how I can generate a backend preview when I select a Mask element under 'content_elements'? In the past, this could be done with \TYPO3\CMS\Backend\View\PageLayoutView, among other things, but that class has been removed.

Maybe someone has an idea?

Typo3 v12.4.24
Mask v8.3.11

Thanks, and keep it up! Great extension!

Can you elaborate a bit - are you talking about the preview that's shown in the page module when editing content of a page, or are you talking about a preview within the relation field?

If it is the former, then previews are possible in multiple ways (event listener, TCA setting for preview renderer, and possibly third-party feature sets). In all cases you can define a custom preview using the core's vanilla methods for preview rendering. And third party extensions like Flux and Mask often provide easier ways to define previews (Flux has a section in the template, don't know about Mask). For support on the core's preview rendering you'll have to search the docs, that would be outside the scope of both Flux and Mask.

But if it is the latter, then the TYPO3 core does not support such a preview and to my knowledge, neither Flux nor Mask provides an override that would support that (and Flux never will, but don't know about Mask).
