Tizen TV webapp navigation with remote & iframe


I am building a Tizen TV app using the web application template (SDK 5.5).

I have a web page with a form that has multiple input texts and a submit button.

On the same page, I have links to other pages and links to social login.

After I open the web app on Samsung TV emulator, I am unable to focus on the different text inputs and navigation links using the TV remote (left/right/up/down) keys.

Do I need any specific changes in the config.xml to make this work seamlessly on all application pages?

Q2- Can I use iframe in the webapp to point to the web application hosted on our servers?
