Extension field type in SAP C4C

Hi All,

My requirement is to create new field as external note on Account header,

So i tried it by Adapting the page and adding new field as the standard suggest.

But it is creating a single line text field as below snap,

I didn't find a way to get it done through Adaptation.

Then I seeked SDK tool to find an alternative to get it through. But unfortunately i didn't get any way which can solve the issue.

I saw the field type of standard Note Field through UI Designer and it is "" but when we try to use the same type in extension it is not available.

Please suggest your valuable inputs on this.

Thanks in advance,
