Answers.Text: I'm actually wanting to do this solely in the control panel entry not on a template output page.  I basically want to be able to relate two channels and rather than pulling all 100 entries that exist in the source channel, I would like to be able to set up the relations field in the admin to filter according to a category.  That way when I create a new entry in the target channel, instead of pulling up 100 entries to choose from, I will pull up say 10 that have the category I selected when setting up the field.

Answers.Text: Lori that code is meant to go into the Dynamic Fields settings. It's not template code for the front end, but responsible for which entries are going to be available in the dropdown field in the Edit Entries view in your CP.

Body: <p>Is it possible to filter relations entries field by a category in a control panel entry?</p>
  
  <p>I would like to relate two channels using the entries field but I have 100 source entries so I was hoping to be able to filter the list by category to narrow down what is shown in the target entry. Similar to how EE Playa works which allows me to choose the category in which to pull the related entries from when I initially set up the custom field.</p>
