One of the most frequent complaints is the fact that the 3dcart Sub Category drop down select boxes are disastrous to navigate for customers. In turn this makes shopping difficult and raises the probability of customer abandonment.
The Cart Designer can remedy this situation by removing the useless drop down select boxes for the subcategories in mobile responsive. The new layout will show your subcategories in mobile responsive as they are on your desktop except on smaller screen widths of mobile devices. Works perfectly with 3dcart Responsive Product Countdown
which makes both your products and sub-categories much more mobile friendly.
