I have a report, and I want to customize its header text length because somehow Zoho "miraculously" trim my Report Header text without even bother to provide tooltip or anything like that for my clients to see the full text. So I browse the documentation and found https://www.zoho.com/creator/help/url-pattern/style-based-urls-for-embedded-forms.html which is broken and very misleading, because not every settings works for header. I have tried to use Form Header Customization from that documentation, with only 'zc_HdrClr' works.

So my question is, did Zoho support this kind of simple customization?
