I don’t know what you mean by ‘forum navigation link.’
Hi John,
I have this same issue. See my other topic here for a better explanation.
http://bbpress.org/forums/topic/wp-menu-does-not-stay-active-when-navigating-forums
Basically, the WP Menu that is linked to the forum is fine until you start to enter subforums and topics.
Same goes if you use a bbpress shortcode in a page and link it to a WP Menu item.
I have the same issue. Basically, the “Forums” button in the main navigation no longer stays highlighted once you enter any part of the forums.
I solved this with some CSS. First, in WP-Admin > Appearance > Menus, i added a custom CSS class to my tabs (at least my Forum tab and News tab). If you don’t see the CSS-classes field, toggle it on in the Screen-Options. For my Forums tab, i set a CSS class of “nav1-forum” and my News tab got “nav1-news”.
Then in my CSS file (style.css), i added this to my Active-tab styles
.bbPress #main-menu #menu-main-menu li.nav1-forums a,
which makes the Forum tab highlighted whenever bbPress is “on” (based on the body class “.bbPress”.
And I added this to my Inactive-tab styles:
.bbPress #main-menu #menu-main-menu li.nav1-news a,
which forces my News tab (which is for my normal “posts” post-type, the blog area of my site), to appear as Inactive, even though its element actually does incorrectly have the class “current_page_parent”.
Of course you may need to adjust the IDs in the css, to match your html.
