Drupal: Add New Criteria to an Existing Automated List (aka View)
Your role in Drupal may not have the proper permissions to complete the task. Contact your site administrator for additional information.
Click Menu in the Administrator toolbar.
Click Structure in the Menu toolbar.
Click Edit for the view you wish to change.
Click on the display you wish to change.
Click Add to add new criteria to either the Filter Criteria or Sort Criteria fields.
Note: Both fields have many, many options, so it is best to search for the criteria you wish to use. Also, don’t be afraid to experiment!
Note: Make sure to select This panel_pane (override) if you want to limit the new criteria to just this display instead of all displays for this view.
Select the criteria you wish to add.
Enter any additional configuration options as needed.
Note: This is often where you will be given the option to make the criteria visible to viewers of your website. If you want viewers to be able to customize this criteria, check the Expose this filter to visitors, to allow them to change it checkbox.
