Question

I am populating a Twitter bootstrap accordion with data from my Rails app and I am looking to be able to filter the data. I have found some nice jQuery plugins but none seem to filter the data. Is this because it is not a simple list? Edit: Not using a list anymore. This is the code I have so far:

<div id="descriptions">

    <% unless @subcategories.nil? %>
    <form class="filterform" action="#">
        <input class="filterinput" type="text">
    </form>

    <div id="list" class="display-subcategory">
        <div class="accordion" id="accordion2">
            <% @subcategories.each do |s| %>
                <% unless s.description == "No description yet"%>
                <div class="accordion-group">
                    <div class="accordion-heading">
                        <a class="accordion-toggle purple-text" data-toggle="collapse" data-parent="#accordion2" href="#collapse<%=s.name.gsub(/\s+/, "")%>">
                                <h3><%= s.name %> </h3>
                        </a>
                    </div>
                    <div id="collapse<%=s.name.gsub(/\s+/, "")%>" class="accordion-body collapse out">
                        <div class="accordion-inner">
                            <%= s.description.html_safe %>
                        </div>
                    </div>
                </div>
                <% end %>
            <% end %>
        </div>
        </div>
    <% end %>
</div>

And this is the plugin I am using: http://anthonybush.com/projects/jquery_fast_live_filter/

Edit: I am no longer going to use this plugin and I am going to attempt to write my own filter function.

I am trying to filter by the name of the items but I can’t figure this out and would appreciate some assistance. Thanks.

This is the jQuery I used to filter my accordion, I used this jfiddle to help http://jsfiddle.net/U8T8p/10/:

    (function($) {

        $('.filterinput').keyup(function() {
            var a = $(this).val();
            if (a.length > 0) {
                children = ($("#accordion2").children());

                var containing = children.filter(function () {
                    var regex = new RegExp('\\b' + a, 'i');
                    return regex.test($('a', this).text());
                }).slideDown();
                children.not(containing).slideUp();
            } else {
                children.slideDown();
            }
            return false;
        })

    }(jQuery));

So this uses a regex to find my accordion headers and hides them if they don’t match the input. Hope this helps someone else anyway.
