I have emailed support but no answer so i try here in the support.
I noticed the portfolio extension you are using where you can select "multiple tags" on your website, see link belowhttps://www.shape5.com/product_details/club_templates/
None of the extension you have for sale have the possibility to have multiple filtering just like yours you have on your own website, do you have this extension for sale ? If yes, where can i find it ? If no, will you consider sell this extension since you already using it on your own website ?
This is a VERY much sought after functionality and no one seems to have a extension on the joomla market for sale.
