We are glad to announce a new add-on from Webgraphiq - “Tabbed Blocks” for CS-Cart v.4 releases.
With this add-on you can embed different blocks into one with tabs for the customer frontend.
One of the biggest challenge to web designers is finding ways to place a lot of information on a page without losing usability. Tabbed Blocks add-on is a great way to handle this and was developed basically for product blocks.
