Is there a way to render content from the issue description field in other places or at the very least render HTML content?
Right now I have made a tab in the issue section displaying this string:
String test = <b> test </b>
but all this does is print out the text as is.
Would appreciate any advice.
Does anyone have any answer for this 
Can you please provide more information explaining what you are trying to accomplish? For example, are you using a Web Panel? https://developer.atlassian.com/server/framework/atlassian-sdk/web-panel-plugin-module/
If so, how are you using it?
Providing that information might get you better answers.
