We have a view using Better Exposed Filters called Programs with an exposed filter on a taxonomy term "Level of Study". I'd like to group this so that the only values in the exposed filters are Graduate and Undergraduate.

I first tried to "group" the terms as follows

enter image description here

but then got errors as follows:

Warning: Illegal offset type in views_many_to_one_helper->ensure_my_table() (line 954 of /var/www/html/sites/all/modules/views/includes/handlers.inc).

enter image description here

I then tried to rearrange the taxonomy so that Graduate and Undergradute terms are parent to the others as follows:

- MFA Degrees    
- Professional Degrees    
- Doctoral Degrees    

- Majors and Minors    
- Modules    
- Interdisciplinary Programs

And this still does not yield the desired result.

So I'm at a loss and opening up a bounty.

First I'd recommend adding a taxonomy term 'Graduate Interdisciplinary Program' to match the 'Undergraduate Interdisciplinary Program'

Configure your vocaulary

Assuming you have these taxonomy terms 'weighted' to their respective parent terms 'Graduate' and 'Undergraduate' you can proceed to configure your view.

Your views page - you'll need to configure fields and filters as you like

Configure the filter criteria as follows:


Content:Has Taxonomy Terms

Vocabulary: Graduate/Undergraduate Programs

Selection Type: Dropdown

Depth: 1

Views Settings

Configure Filter Criteria

Tick - Expose this filter to Visitors, to allow them to change it.

Tick - Grouped Filters

Widget Type - Select List

Label - 'Area of Study'

Views Settings

Finally configure the table as you have it in your screen-shot ... ideally without the overlap of the term 'Multidisciplinary Program' ...


  • Can you include any screen shots or urls? I'm looking to get a defacto, how-to answer!
