Remove (stock level) from product listing

There is no manual describing all the views. There are just too many of them.

When you want to change some text, the best is often to just override by editing your language file as explained there:
www.hikashop.com/en/download/languages.html#modify

That's what you should do there.

If you remove the words in the language file, it won't display... The result will be the same.

You can indeed also do it with css by adding the CSS below in the front end CSS file that you can edit via the interface in the Display tab of the config:
.hikashop_product_stock_count{ display:none; }

If you want to edit the display of the product information on products listings, it's one of the files "listing_img_*" of the view "product" that you need to edit.

If you want to edit the display of the product information on products page, it's the file show of the view 'product that you need to edit.

When SEF is turned off, you can see: &ctrl=XXX&task=XXX
if the task is not in the URL, it means that the task is "listing".
The ctrl part defines the view name and the task part defines the file name in the menu Display->Views.

The views of HikaShop are like real views of Joomla. RedShop views use tags so that it's easy to move around for you. On the other end, it gives you less possibilities when you really want to customize it profoundly. I'm sure that having code directly instead of tags in our views is really good for people knowing at least a bit of PHP/HTML because then you can really do what you want and are not limited to only the things that we thought of when designing it.
Our goal is that you don't even need to see the views code for most uses by just changing the layout options in HikaShop and also by simplifying them into small bits.
If you look at the listing_* views, we improved them since that thread started and now it's quite easy to know how to move the different parts of these views around. We're moving towards that end for the product page too with the latest version.
