category menu

Hi,

If you're talking about the categories listing being displayed as an accordion on the left of the screen of the demo website, that's a module which generate the entries dynamically based on the categories. You don't need to create menu items one by one for that.

It's not a problem.
It's the one "categories listing 2 levels" which is installed by default with HikaShop.

I don't understand what you mean by that.

It will use the styles of the standard accordion system of mootools which is in joomla by default.
It's highly probable that your template doesn't redefine these styles for such display.
So you'll probably have to edit your template CSS to duplicate the CSS style for the classes of the mootools accordion that it is using here.

These modules are not removed when you uninstall HikaShop. Thus, they are not installed a second time once you installed HikaShop once on a website.

You can always recreate them manually as they are just pre configured instances of the HikaShop content module:

Otherwise, after uninstall, you should delete all the table of HikaShop in the database via phpmyadmin and then when you install HikaShop it will put them back in. Note that it means that you will loose your products data, etc.
