Paypal & custom field

When you edit your messages after posting, we don't see it all the time. You should create a new reply so that we can see it. I didn't see your questions so I didn't answer.

1. You can't have several custom fields with the same name indeed. There is no link between the 2 custom fields. The code I told you to add says to not display the custom item fields if the field domein is not Ja. So if you need several custom fields couples, You will have to have some other code to handle that.
In that case you should add something like that in the foreach few lines below:
if($this->element->domein!='Ja' && $fieldName=='domeinnam') continue;

2. You can edit the views via the menu Display->Views. You can edit the CSS in the config under the tab Display.

3. Everything is possible if you code it. It's just not possible by default. You would have to edit the view and add some check on the field.

4. It's to display the items in the listing of products on the order.

1. The code in my previous post would handle that.

2. Wait, you're talking about the number of columns of the listing ? That can be changed in the hikashop options of your menu/module that you can access via the menus Display->Content menus/modules

3. We can do it for a small fee. You can use our contact form to request a quote.

I don't particularly like when people bump threads because we didn't reply in the hour and they want their answer...But for posting additional information/questions or if your question slipped our queue, that's not a problem.

The images size do not change when changing the number of columns of the listing.
The thumbnails size of listings is controlled by the thumbnail width and height options located in the tab Files of the configuration. If you change them the images size will change. If you increase them, the images will get blurry so you will have to delete the folder media/com_hikashop/upload/thumbnail via FTP so that HikaShop can regenerate the thumbnails files with the new size.

So you want to increase the margin between each item box ? Please do a screenshot to explain what you would like to change and give a link to that page in case we need to test the CSS.

So you want to remove the white background color ?
You can do that in the hikashop options of your menu/module. There is a color option in the bottom left corner of the edition screen.

If I'm following you correctly, you want to have your 5 products per line like on your screenshot 2, without increasing the width of the main area. Is that right ?
If so, I don't see how you could do that.

We're planning next release for the beginning of the week so that won't be possible

Points 1 and 3 are things that we want to add in the future yes. For point 2, I don't see how we could fit more products than possible in a defined space. The product display is already quite scalable...You can change the image size, change the text size with CSS, change the number of products on a line, etc.
