Hi,

I have a class named Document which extends DataObject and a class named DocumentAdmin which extends ModelAdmin. When editing a Document through the ModelAdmin view, I would like to modify how the ModelAdmin displays the title text of the Document in the very top of the page. The reason for this is that the Documents have usually very long titles which will take up a lot of space as they go to a second row. If you need, I can post a screenshot to demonstrate the problem.

There multiple ways to do that.

The simplest way would be to copy the template "framwork/admin/templates/CMSBreadcrumbs.ss" to "mysite/templates/CMSBreadcrumbs.ss" and change its content to limit the characters of your title.

...
<% if $Last %>
	<span class="cms-panel-link crumb last">$Title.LimitCharacters(50).XML</span>
<% else %>
...

Though, this will change all the breadcrumbs where it is used, but I guest that this is not that bad.

The correct way would be to:
- override GridFieldDetailForm->Breadcrumbs() to trim the Title: "'Title' => substr($this->record->Title, 0, 50)"
and
- override ModelAdmin->getEditForm() to remove the original GridFieldDetailForm component and add your new GridFieldDetailForm component

Thank you, Devlin! :)
