I don't know if there is a way to do it, but it would be nice if mods can be filtered only for forge, in the same way that it is done with the fabric tag.
It is very annoying to look for mods and that a lot of mods appear that are not going to work.
The main thing on the page is forge mods, fabric only has 10% of mods and it has a tab.
I know that the modloader can be selected from "game version" but that way I can no longer select the version, it would not be very pleasant if mods from 1.7 appear
I think the best thing is to make a tab in the same way that fabric has or that multiple things can be selected in "game version" (that would also make it more useful)
