Drupal: Views taxonomy exposed filter, show tree/hierarchy in drop down menu

I have an exposed taxonomy filter that allows the user the filter by term. The vocabulary is 2 tiers, however in the exposed filter menu the hierarchy appears flat.

Is there a method/module to show the hierarchy with indentation or prefixing child terms with "-", similar to the taxonomy term selection menu from the node edit form itself.

SOLUTION:

The filter Taxonomy: Term ID (with Depth) will display the option "Show Hierarchy In Dropdown" when you select the Dropdown widget.
