How can I pass display exposed filter in views-view-unformatted.html.twig?
Try using Views Exposed Filter Blocks.


Use the Twig Tweak module and embed the exposed filter block in your template with code like this: {{ drupal_block('views_exposed_filter_block:my_view_id-my_views_block_id', wrapper=false) }}.
You can also just place the exposed filter block in any region.
