I installed JA K2 Filter and placed a module in section-1 with default settings in your documentation, but it looks totally different from the demo site.
Demo page code:
<section class="wrap has-slideshow t3-section t3-section-1 ">
<div class="container" ><div class="t3-module module search-now " id="Mod106"><div class="module-inner"><h3 class="module-title ">Search Now<div class="module-ct">
<form id="jak2filter-form-106" name="jak2filter-form-106" method="POST" action="/index.php/en/component/jak2filter/?Itemid=147">
My code:
<section class="wrap has-slideshow t3-section t3-section-1 ">
<div class="t3-module modulesearch-now " id="Mod122"><div class="module-inner"><h3 class="module-title ">Keresés<div class="module-ct"><form id="jak2filter-form-122" name="jak2filter-form-122" method="POST"
action="/hu/component/jak2filter/?Itemid=104">
Best regards
