collapse

So, I have a navigation that is a list and has sublists and sublists. Basically, the nav is by default collapsed, but if people click on a page that's in a sublist, I want to show the parent list. And if it's a sublist of a sublist, I need both parent lists to show. I have it set up, but, I don't like putting 5 .parent().parent() 's to traverse upward to expand the list. Is there a more efficient way? the HTML: <div id="lesson-sidebar"> <ul> <li><a href="index.html">Welcome to Beat Basics and Beyond</a></li> <li><a href="table-of-contents.html">What's in this course?</a></li> <li><a href=

I used bootstrap menu for my app. It looks like this: but when I change window size to smaller, it disappears - looks like this: It disappears when its about ~965px wide (so its probably 979px). I tried this solution , didnt work. May be I'm mixing bootstrap 2 and 3? This is my menu code: <div class="navbar navbar-inverse navbar-fixed-top"> <div class="navbar-inner"> <div class="container"> <a class="brand" href="/">Digrin</a> <div class="nav-collapse collapse"> <ul class="nav"> {{ request.path }} <li{% block nav_stocks %}{% endblock %}><a href="/stocks/">Stocks</a></li> <li{% block nav

I am sure this is a very basic question: In R I have 600,000 categorical variables - each of which is classified as "0", "1", or "2" What I would like to do is collapse "1" and "2" and leave "0" by itself, such that after re-categorizing "0" = "0"; "1" = "1" and "2" = "1" --- in the end I only want "0" and "1" as categories for each of the variables. Also, if possible I would rather not create 600,000 new variables, if I can replace the existing variables with the new values that would be great! What would be the best way to do this? Thank you!
