Sorting a view basing on the value of a boolean field I have a content type X. A view is used to display this content type (X), as a table. The content type has a field called "Preferred" which contains boolean values. I need to sort the table so that the "Preferred:true" items display at the top of the table.

How can I achieve it?
Add a new Sort Criteria sorter that sorts based on that field. Make sure it's at the top of your list of sort criteria.

If you don't want there to be a column for it in the table, click "exclude from display" in the field settings.
