Oh, I’m a plonker about the Code Snippet plugin – of course!!
With regards to the mock-up, what you have suggested there is exactly what I am looking for. Preferably with a paragraph separator between categories rather than line-break – if at all possible. And perhaps the parent categories could be in bold?
Industry/Sector: Agriculture, Healthcare, Logistics
Role/Function: Coaching & Mentoring, Commercial/Legal/IP, General Management
