Multiple product selection from product search help pop up.

Dear All,

I would like to select multiple product items at time from product search help.

I have done required changes in product search help html page and now able to select multiple items.

But after selecting 2-3 products and click on 'Choose' button. Its navigate to product list table view. In product view its shows only one product.

I checked in do_prepare_output method, there also in collection, it shows 1 entity.

Could you please help me? Let me know where it goes wrong.

Thanks,

Vikas
