Nested Relations Plugin

Using this plugin

To install this plugin, extract this archive to /plugins/dominicmercier/nikeid and migrate the database by performing one of the following:

1. Log out and sign back in to the back-end; or
2. Run CLI command php artisan october:up

To view the plugin click on NikeID in the back-end area.

Actual result

1. Select the Hockey Glove product.
2. Go to Layers tab.
3. Click Finger layer. A popup form should appear.

As you can see, each layer can be available in 6 various colors. Each colors is displayed in a checkbox.

Expected result

The colors relations look good if we have a small number of colors. It would be better if we could add|remove color associated with this layer with a complete October back-end list view.

I usually do this by creating a partial that render relation using:

relationRender('layers') ?> in a controller.

Which looks like this:

Anyone know how to do this kind of relations inside another relations?
