Advance filter for K2

Posted on 26 March 2019
It works great, most useful for custom fields option. I can see products with many filter option.
Ease of use
You must know K2 for this as it work only for K2
Support is quite nice i found, for any conflict issue, i got fixed very soon,
Not so good as it more relate with K2 part so you must know K2.
Value for money
Full value for money.
I used this to: It works very fast to filter the k2 items with different k2 options.
I have blog site with K2 and using this with JA multi language extension.
both works great!
Nice work !

Filter not usefull for me

Posted on 12 February 2019
Very limited use. No free content can be displayed in the filter area.
Ease of use
Goes so
About general portal, answers are usually very short and not always understandable.
Very close
Value for money
You have to buy a package with several tools, even if only the filter is desired. It is too expensive for that.
I used this to: It is no longer used. The company was so fair and refunded the purchase price.
Owner's reply: Hi,
Sad to hear the extension does not meet to your expectation.
It would be like to add address the issues you are facing in extension, I tried to look on support forum with your name, but its found.
Can you open a support thread on our official support forum or Ticket help-desk : ,
So we are able to check the issue you are facing and get it fixed for you.

Thanks and Regards

Very slow.

I say Excellent, but...

Posted on 12 September 2014
I say it is excellent in terms of search and sort of k2 items and categories,but the major problem I face is that it is not designed to be responsive and it does not fit in responsive templates.
Congratulations to the Joomlaart team for a very useful extension. What makes these guys different though is their excellent support when in need.

Dear Sirs! Thank you for a such great extension! I've tried to play with it on your demo site and have noticed, that 'slider' doesn't work on a touch-screen devices.

Perhaps you just have to change event-handler to the new one. From 'mouse-over' to 'touch-???'

But extension in any case - one of the best for K2. Thank you!

Great extension

Posted on 02 May 2014
great extension and excelent support... I'm very happy with this component :)
Flawless. Worth every penny (cent) of the $50 for a year's membership to the extension club. If you have a large quantity of items in a K2 category (or multiple categories) and want to make it easy for your users to find what they want then this is for you.

With the multi-site licencing structure this tool will pay for itself 10 times in the year!

My only gripe is that I didn't spot the float that was messing up my divs for 10 minutes....oh well, if that's it then I'm a very happy bunny.
This is great extension and addition to my website. I'm glad I added it. The JA support was awesome also, they answered and helped me with all the questions I needed.

Great Extension

Great extension,

It’s a great extension and very easy to use and customize. It worked exactly as I wanted it to work!

A slight bug that occurred in the keyword search field was solved from JoomlArt support team in less than 24hrs.

I would recommend this extension to everyone that wants to create a search for K2 and specifically filtering by tags.
