Allow Multiple Topics to Be Assigned to a Post

Currently, selecting only one topic is often not enough to accurately describe a post. In many cases, a post naturally belongs to multiple topics, and allowing only a single selection makes categorisation less effective.

It would be great if members could assign multiple topics to a post where appropriate. This would improve discoverability, filtering, and search, while ensuring posts appear in all relevant topic feeds.

Examples:

• A post about using AI to generate social media content could be tagged with AI, Marketing, and Content Creation.
• A discussion on CRM automation using email workflows could be tagged with CRM, Automation, and Email Marketing.
• A WordPress plugin update that includes new API endpoints could be tagged with WordPress, Development, and API.
• A community event teaching business networking could be tagged with Events, Networking, and Business Growth.
