boards customization

Rather than add more JS... you could try creating a custom forum page (this is different than a stand alone custom page, and the naming convention would need to be something like ForumPage.Helldriver, similar to the instructions here), then applying that to the Helldriver board via the admin > Helldriver (manage) > content > Custom Pages.

This would then allow you to add a custom content area or component below the search bar with text specific to Helldriver, that would only appear on this particular board that has this custom forum page/layout applied to it.

As for the search bar issue, you should be able to add a text string specific to search bar on this custom forum page. something like..

page.search.post_from_search@page:ForumPage.Helldriver@component:search-encapsulation = Search Helldriver Board

 Remeber though, if you create this and push to prod from studio, you'll need to manually set the custom page for the helldriver board in prod after the push. But hey, less JS to have the page load.

Hope that helps.
