Webform two dependent select lists I have a content type "course" and a taxonomy vocabulary "Course categories" and a Webform
"Register" the user will register by choosing the course category in select list then use the course related to this term .

Now i have a list for terms and a list for courses 
The problem is i don't know how to link between the two lists so the courses list show only
the correct course
Install conditional fields module and it creates relationship between fields.
