When we go to a specific x-cart category, we can put there some custom content above the category thumbnails. We need to modify skin1/customer/main/subcategories.tpl and just after the h1 tag (or any other place we want it to show)
{if $current_category.category eq “100”}show cusotm contents, prescription glasses{/if}
{if $current_category.category eq “200”}show cusotm contents, men’s glasses{/if}
{if $current_category.category eq “300”}show cusotm contents, women’s glasses{/if}
replace “100,200,300” with the category id
