I would like to customize the groups page, at least to add a paragraph of text above the group list.
As far as I understand, ultimately I’d have to create a theme component.
But is it possible to do something without resorting to this?
Then I thought of using the Versatile Banner component but it’s already in use in the other pages of my forum. Is it possible to use another instance of the same plugin with a different config so that it displays only on /g and with another content? If so, how?
The discussion on that page eventually put together a solution, but it might be a little hard to pull together, and Discourse admin navigation has probably changed a bit.
This kind of thing is done by creating a simple Theme Component:
Go to Admin → Appearance → Themes & components
Click the Install button, and in the dialog choose “+ Create New”
Name it something like “Groups page intro” and leave the Type selector on Component
Click “Create”
Select your theme(s) and click the Edit Code button.
