Feature Request - Multi Topic option in the community posting

Hi, I suggest that user select multiple topic when they write a post. Basically, the topic of the post is a tag, which people use it to filter the posts.

For example, this post is related to Idea topic, but also related to Feature request topic. If we allowed multiple topic in the post, this post appears to people who want's to see the #Idea related post and #Feature Request related post
