Dynamically adjust argument or filter to views entity reference filter based on value from select list in form I have a entity reference field that references a taxonomy term from a vocabulary named "fund".  Now I'm needing to add a fiscal year field to the fund terms to allow us to have different budget lines for different fiscal years.  Some of these funds will have the same name, but be from different fiscal years, so I now need to add a fiscal year dropdown list before the autocomplete entity reference field mentioned above.

Say the dropdown has two values FY17 and FY18, I'd like the views entity reference filter view to receive the selected value for fiscal year, and apply that as a filter to the views entity reference filter.  How can I accomplish this?  Alternatively is there a better way to accomplish this?

For example:



I looked at Dynamically change views entity reference filter based on current form value but it doesn't seem like it quite fits what I'm trying to do.  I could be wrong.
The simplest answer ended up being to use Entity Reference View Widget which allowed me to build a view for selecting the entity desired.  This was nice because it allowed me to add some additional information and filtering the the approach I was hoping for in my question didn't allow.  Unfortunately, it also moves me further from being able to update this site to Drupal 8 because this module doesn't exist for Drupal 8 because the maintainer decided to let another module that isn't released yet, cover this functionality for Drupal 8.  I would still welcome answers about how to do this in a more forward compatible way.
