I am using Website Form Builder module 12v

Also displaying res.partner model form in website by using Website Form Builder module.
But problem is i can't set domain in a field in website form.

Where have multiple Many2one field. like as division_id, district_id

district model is below:

name = fields.Char(required=True, size=100)
division_id = fields.Many2one('divisions', required=True, ondelete='cascade')

I need to set domain division_id in district model
by default district will be display empty. After select division, district value will be display based on division_id.

It would be grateful for me, if anyone can help me about this issue.
