in drupal 8 core views, in any view you can add header or footer field with "Rendered entity - Custom block". When you do so, it asks for the block id, which appearently is machine name of the block.
A search form block has an id equal to bartik_search
and that will make the search box to display.
But i have my own custom block created and it has Machine name: modallink
and i want it to display instead.
Problem is, when i enter modallink
into the "block id" box, it doesn't work. Nothing gets rendered.
What is ID of my custom modallink
block?
Am I using the "Rendered entity - Custom block" field incorrectly?
