Visa type and Sub-type for Sole representative Dependent

Hi,

What type of visa and sub-visa type we need to select for Dependent of Sole representative visa.

My company offered me Sole representative visa and i have filled the form with out any issues. Coming to my wife who is dependent on me [she is going to travel with me, she has 9 years experience in software and planned to work in uk ]. Can any one help me on what type of visa and sub-type she needs to select ?

We selected "work --> Dependent more then 6 months " option from drop down but its asking to fill "UK sponsor" section which confused me!

Please help.

regards,
Chandra
