Yii Time Table genaration

Yii Time Table genaration

I am new to yii framework. As a project we do a school information
management system. In that system we have to create a time table.
The time table has 5-days(Monday-friday) as columns and 8 periods as rows.
In a cell there should be two dropdown lists for subject and corresponding
teacher. All together there are 80 dropdown lists.So I have to write code
for all 80 dropdowns.
Is there any way to minimize the code for dropdowns or can anyone suggest
a better way to do this.
(In the beginning of the time table form class is select and according to
that subjects are updated to dropdowns. From the subject can select the
corresponding teacher)
