title: dependent drop-down list in odoo 8 / open erp
body: <p>I have made two drop-down lists. Second drop-down list's data is dependent on first drop-down list's chosen value i.e it changes dynamically.<br>
  First DDL is <strong>Region</strong>  which contains <strong>one or many Departments</strong> that provide second *DDL.</p>
  
  <p>I have tried multiple methods like <a href="http:////https://stackoverflow.com/questions/26591360/dependent-drop-down-in-odoo-open-erp" rel="nofollow noreferrer">this one</a> but didn't find any relevant solution.</p>
  
  <p>would somebody like help me?<br>
  *DDL = DropDownList</p>
