Generate only parent taxonomy terms in a block I need to generate a menu for parent taxonomy terms. 

How would I go about doing this? I'm also looking to generate these terms in a block.

I have a views set up right now that displays just all taxonomy terms. I can't figure out how to filter out child terms. Is there a filter for this, or do I just have to manually create each category item?
In Drupal 7 to only show parent terms you add a “Contextual Filter” and add “Taxonomy term: Parent term,” then set “Provide default value” to a “fixed value” of 0.

That will filter out the child terms.
