EL Expression to Hide Profile Field based on LOV Selection

Summary

What EL expression is used to hide a field based on the user's selection from a LOV?

Hi all, 

I'm wondering if anyone has set up an EL expression to hide fields on the talent profile based on a selection from a list of values? For example, in our "Education and Degrees" content section, if the user selects the "High School or GED" value, we do not want the "School" field (a list of values) to show, and only show the "School Name" field (a text box). This is because we won't have any high school names loaded in the list of values, only post-secondary schools, and they can instead just type in their high school name. I'm wondering
