Create a view to display the list of content created by user and any published content I am creating view for displaying content list and some exposed filters. I wanted to display all published content of any user and all content created by user(current user).
Currently i am able to display only own content list by using contextual filter:


Click "Advanced" > "Contextual Filters"
"Add" > "Content: Author uid"
"Provide default value" > "User ID from logged in user"
Save


How can i display in list a combination of All published contents from all authors + published and unpublished contents of logged in user?
You anyway want to display all content from all the authors and current user so no need to add contextual filter, then it's going display all the content from your site with logged in user's content too.
