Here is a javascript to hide/show categories.

Code:: $(function(){$('.main-head:has(.page-title)').prepend('<a class="collapse tcatCollapse" id="collapse_c_cat1" href="#top" style="visibility:hidden;float: right;margin-top: -3px;"><img src="http://i.imgur.com/d7jXnmJ.png" alt=""></a>');$('.main-head:has(.page-title)').mouseover(function(){$(this).find('a.collapse[id]').css('visibility','visible')});$('.main-head:has(.page-title)').mouseout(function(){$(this).find('a.collapse[id]').css('visibility','hidden')});$('.main-head a.collapse[id]').click(function(e){e.preventDefault()});$('.main-head a.collapse[id]').attr('onclick'," if($(this).closest('.main-head').next('.main-content:first').css('display')=='none') {my_setcookie($(this).closest('.main-head').find('.page-title').text()+'_ct','0',10,0); $(this).closest('.main-head').next('.main-content:first').slideDown(500);$(this).find('img').attr('src','data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABIAAAASBAMAAACk4JNkAAAACXBIWXMAAAsTAAALEwEAmpwYAAAAKlBMVEX///8dNlIdNlIdNlIdNlIdNlIdNlIdNlIdNlIdNlIdNlJSZn16ip3k6/JkLhjLAAAACnRSTlMACkVWWZerzdXxurlICgAAAF5JREFUCNdjYGAQDp9ZasgABExZq1atWqYAZHmsAoEWoFAXmLVCgUFsFQQkMlhBWYsZoqCspQxVUNZyhlmrVt29e2fVqpUg1pkzp0EshCxCB8IUhMkI2xAuQHIVzKUAh8ZUIpv14jgAAAAASUVORK5CYII=');$(this).closest('.main-head');$(this).closest('.main-head').removeClass('collapsed')} else {my_setcookie($(this).closest('.main-head').find('.page-title').text()+'_ct','1',10,0); $(this).closest('.main-head').next('.main-content:first').slideUp(500);$(this).find('img').attr('src','http://i78.servimg.com/u/f78/18/17/62/92/cat_ma10.png'); $(this).closest('.main-head').addClass('collapsed');}");$(document).ready(function(){$('.main-head a.collapse[id]').closest('.main-head').each(function(){if(my_getcookie($(this).find('.page-title').text()+'_ct')=='1'){$(this).next('.main-content:first').css('display','none');$(this).find('a.collapse[id] img').attr('src','http://i78.servimg.com/u/f78/18/17/62/92/cat_ma10.png');$(this).closest('.main-head').addClass('collapsed')}else{$(this).next('.main-content:first').css('display','block');$(this).find('a.collapse[id] img').attr('src','data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABIAAAASBAMAAACk4JNkAAAACXBIWXMAAAsTAAALEwEAmpwYAAAAKlBMVEX///8dNlIdNlIdNlIdNlIdNlIdNlIdNlIdNlIdNlIdNlJSZn16ip3k6/JkLhjLAAAACnRSTlMACkVWWZerzdXxurlICgAAAF5JREFUCNdjYGAQDp9ZasgABExZq1atWqYAZHmsAoEWoFAXmLVCgUFsFQQkMlhBWYsZoqCspQxVUNZyhlmrVt29e2fVqpUg1pkzp0EshCxCB8IUhMkI2xAuQHIVzKUAh8ZUIpv14jgAAAAASUVORK5CYII=');$(this).closest('.main-head').removeClass('collapsed')}})})});

But this code is not working for me, because I have edited my templates. So anyone can help to make if working for my forum?

In my opinion, hide/show category only need this

Code:: $('selector').click(function(){$('category selector').toggle();});

If there are so many category and selector, use

Code:: $('selector').click(function(){$(this).next/prev/siblings/parents/children/...().toggle();});

You can use cookie to make it hide/show forever until you click the selector (find cookie's instruction in box Gist). The code that you show me is so complicated :-s
