Implementing a custom column for existing item typesΒΆ
Implementing a custom column for existing item types is not any different from implementing a column for your own custom item type.
The process involves adding a bit of configuration to enable the column:
netgen_content_browser:
ezlocation:
columns:
my_column:
name: columns.ezlocation.my_column
# Either specify a template or a value provider identifier
template: '@App/ngcb/ezlocation/my_column.html.twig'
# value_provider: ezlocation\my_column
And then you need to either create a template that will render the cell of the column, or create and register a Symfony service that does the same. For more details, read the relevant sections in the chapter about creating a custom backend.
