cool so all I have to do is use html instead of markdown.
So the banner will work if someone tries to reply &/or create new topic within category? Where if I understand correctly your request is relate say to new topic button theme-component?
With your js would you just create a new theme-component & upload the *.js file? Is there any thing else needed in the css etc parts? or will it just work?
And if ibwant dialog prior to link button what eould I be required to do code wise. my apologises still learning
