HTML - CSS - quick fix needed

Hello I have a small ecommerce site which is a upgraded template of WordPress. Recently there was a work done on search filters. From functionality everything works fine. After some time we found there is a problem in Internet Explorer browser. When you try to use the filters and you make them active or inactive it cause a broken layout in IE. Please have a look and try it yourself. Dont forget to see in in IE :-) Im also attaching screenshot. I am strongly convinced this is CSS / HTML problem. Good coder should be able to fix this within 1 max 2 hours. IMPORTANT: the functionality of the site and especially filters must not be damaged. Only design solution no extra scripts etc. ## Deliverables Im able to pay directly into your Paypal account. For successful coder I will have more work possibly on regular basis. You must have some rating.
