Re: Tips required to use sliding login panel in place of the traditional bp bar.
A couple of considerations here.
If you use this login panel, you’ll most likely want to disable the BuddyBar. Just something you might want to think about.
Secondly, play around with that jQuery script. When you have the script actually toggling, then the next step is to implement the BP login form.
For this, you’ll want to examine the bp_login_bar() function (found in wp-content/plugins/buddypress/bp-core/bp-core-templatetags.php – line 589 and on).
You can either call this function directly or create a copy of the function and modify it for your needs.
You’ll probably also need to style it so it works the way you want it.
Hope that helps!
