Ftl rendering issue from electronic text

[Vikram Varma Dantuluri]

Hi,

I am trying to use electonic text as ftl.

For example in Cmssite there is a content with contentId "CMSS_DEC"  and
this content
is associated with contentId "CMSS_Demo_header" it contains the below
html content

<div id="header">
       <h1>This is the header!</h1>
 </div>

After rendering, classes, id's and other
attributes of the html contents are missing?
After inspecting the rendered code it looks like below
<div>
    <h1>This is the header!</h1>
 </div>

Is it an issue or am I missing something? Any pointers on where to check
would be very helpful

We are trying to render ftl from Screens as below:

<content content-id="CMSS_DEMO_HEADER"/>

Thanks
Regards,
Vikram
