Does Not Add Objects Hierarchy when Click Webpage to Create Shared OR

Helllo, 

I am currently creating a share OR.
But the issue that I am currently facing isthat the features that is on the webpage did not added into object hierarchy, which does not allow me to create script.
i have to manually add the components one by one.

For example, here is the webpage that I want to add into shared OR.
in this webpage contains input box for username and password and a Sign In button.

So, when i click Add Object into Shared OR, supposedly there is three chilc objects added into object hierarchy.

However, when I click the form to be added into Objects shared OR, there is no clid objects added into the object hierarchy.

Can anyone help me to solve this issue?

Thanks.
