how display check box based on another chckbox value using angularjs?

i have added my code.i am new to this technology pls any one help me out.i have two different checkbox list 1st one is Select Stores 2nd one is Select your device Company name .baesd on first checkbox checked value 2nd(Select your device Company name) checkbox list should come achievements: achievement :Based on first check box list(Select Stores) values 2nd checkbox(Select your device Company name) list should come

Example: if i select Sai Stores in Select Stores list .Select your device Company name list show should show only Sai Stores

Example2 : if i select Sai Stores,Sri Ram Stores in Select Stores list .Select your device Company name list show should show Sai Stores and Sri Ram Stores

example3 :

if nothing is select in that Select Stores list . Select your device Company name list should be hide or not visible

example 4:now i have already selected Sai Stores in Select Stores list.Select your device Company name list should show only Sai Stores .here instead of that its showing both in Select your device Company name list

if matched then only second list of checkbox should show other wise it should be hidden http://ift.tt/1MXlq6m
