1) when you assign a product to subcategory, it does not automatically assign the product to the main category as well, you need to select the main category and the subcategory in the list to assign it to both.
2) The Power Store side menu does not collapse like Power Store 3 did.
3) since the menus no longer collapse, those icons arte no hidden. if you want to show them, in the accordion_styles.css file, change:
dl.nestedaccordion dt.accordionclear, dl.nestedaccordion dt.open.accordionclear, dl.nestedaccordion dt.accordionclear:hover, dl.nestedaccordion dt.open.accordionclear:hover, dl.nestedaccordion dt.open.selected.accordionclear, dl.nestedaccordion dt.selected.accordionclear {
background-image: none;
}
to:
dl.nestedaccordion dt.accordionclear, dl.nestedaccordion dt.open.accordionclear, dl.nestedaccordion dt.accordionclear:hover, dl.nestedaccordion dt.open.accordionclear:hover, dl.nestedaccordion dt.open.selected.accordionclear, dl.nestedaccordion dt.selected.accordionclear {
/*background-image: none;*/
}
