Hi, is there a way to allow users to insert HTML tags and render them in the discussion post?
ikramy Not directly. Flarum uses https://s9etextformatter.readthedocs.io to format and render posts, and it has a wide range of options and customization abilities. Markdown and bbcode support are implemented through that, as are most additional formatting features.
See https://discuss.flarum.org/d/25873-using-plain-html-in-discussions/10 for a list of why this might not be the solution you need.
Please explain what problem you are trying to solve, we might be able to suggest a better solution 😃
