java script trick to hide the "filter" in a django admin view

list_filter_collapse.js

(function($){
ListFilterCollapsePrototype = {
    bindToggle: function(){
        var that = this;
        this.$filterTitle.click(function(){
            that.$filterContent.slideToggle();
            that.$list.toggleClass('filtered');
        });
    },
    init: function(filterEl) {
        this.$filterTitle = $(filterEl).children('h2');
        this.$filterContent = $(filterEl).children('h3, ul');
        $(this.$filterTitle).css('cursor', 'pointer');
        this.$list = $('#changelist');
        this.bindToggle();
    }
}
function ListFilterCollapse(filterEl) {
    this.init(filterEl);
}
ListFilterCollapse.prototype = ListFilterCollapsePrototype;

$(document).ready(function(){
    $('#changelist-filter').each(function(){
        var collapser = new ListFilterCollapse(this);
    });
});
})(django.jQuery);

I wrote a snippets for menu collapse and single element menu collapse.

It's a fork from abyx code, I've just extended it.

If a filter was previously activated the element menu related to this will start as opened.

The filter menu starts closed as default.
Hope this helps
