Hi!

There is no official way of doing this unfortunately. The Catalog UI is in need of a refresh if you ask me.

It should be possible to achieve it with a custom ViewConfiguration and some dojo/dijit code. Here is a pointer in the right direction:

ViewConfiguration (backend):

First of all you will need to create a custom view configuration. It must have the same key as the default view. Here is an example:

[ServiceConfiguration(typeof(ViewConfiguration))]
public class CategoryViewConfiguration : ViewConfiguration<NodeContentBase>
{
    public CategoryViewConfiguration()
    {
        Key = CommerceViewConfiguration.CatalogContentListViewName;
        LanguagePath = "/commerce/contentediting/views/cataloglist";
        ControllerType = "catalog-ui/CatalogContentList"; // The default ControllerType is epi-ecf-ui/widget/CatalogContentList. You have to create your own and inherit from default.
        IconClass = "epi-iconList";
        SortOrder = 250; // Needs to be lower than 300 which is used by the default configuration.
        Category = CommerceViewConfiguration.CatalogCategory;
    }
}

Dojo/dijit widget (~/ClientResource/catalog-ui/v1/CatalogContentList.js):

define([
    'dojo/_base/declare',
    'dojo/_base/lang',
    'epi-ecf-ui/widget/CatalogContentList'
], function (declare, lang, CatalogContentList) {
    return declare(
        'catalog-ui/CatalogContentList',
        [CatalogContentList], {
            // Add new and/or override logic here
    });
});

Module.config sample to map catalog-ui to ~/ClientResources/catalog-ui/v1 path:

<?xml version="1.0" encoding="utf-8"?>
<module>
  <clientResources />
  <dojo>
    <paths>
      <add name="catalog-ui" path="catalog-ui/v1" />
    </paths>
  </dojo>
</module>
