question regarding hidden fact CSS link
SK
Dear community,
I'm not sure if this user group is the right place for my question, but I figured this is where the XBRL community hangs out, so I'm just going to give it a shot :-).
When using a hidden fact (for example an EnumerationItemType) in the context of IFRS/ESEF (where these elements have only recently been introduced) we apply the custom CSS property -ix-hidden in a style attribute on a tagged HTML element. Please refer to the WGN, section 8 or the ESEF reporting manual (Guidance 2.4.1).
We have a use case where a company wants to apply two hidden facts to the same HTML element (e.g. a <p> element).
For example, in the IFRS taxonomy it seems reasonable to use both:
- ifrs-full:InvestmentInAssociateIsMeasuredUsingEquityMethodOrAtFairValue
- ifrs-full:InvestmentInJointVentureIsMeasuredUsingEquityMethodOrAtFairValue
on the same content, resulting in the following ix:hidden section:
We tried different approaches to apply multiple facts to the same HTML element, e.g. <p style="-ix-hidden:id-1 id-2"> or <p style="-ix-hidden:id-1;-ix-hidden:id-2">.
In both cases the second fact is not recognised by Arelle or the iXBRL viewer.
Does anyone know what the correct syntax would be -- if there is one? This does not appear to be covered by the (i)XBRL specification, and the working group note does not refer to such a use case either.
Thanks! Sacha
