Problem:

The user wants to create a taxonomy called "Artists" for a CPT "Record" with the following restrictions:

Limit the taxonomy to a single selection.
Ensure the taxonomy is "childless," meaning no parent-child hierarchy is allowed.

Solution:

Limiting the Taxonomy to a Single Selection:

Toolset does not natively allow restricting taxonomies to a single choice. However, you can achieve this using custom JavaScript and CSS to ensure only one checkbox can be selected in the admin panel.

function restrict_taxonomy_to_single_selection() {
    if (is_admin()) {
        ?>
        <style type="text/css">
            #newartist_parent {
                display: none; /* Hide parent selectors */
            }
        </style>
        <script type="text/javascript">
            jQuery(document).ready(function($) {
                $('input[name="tax_input[artist][]"]').on('change', function() {
                    if ($(this).is(':checked')) {
                        $('input[name="tax_input[artist][]"]').not(this).prop('checked', false);
                    }
                });
            });
        </script>
        <?php
    }
}
add_action('admin_footer', 'restrict_taxonomy_to_single_selection');

Creating a "Childless" Taxonomy:

In Toolset > Taxonomies, change the taxonomy type to a flat taxonomy (like tags) instead of hierarchical. This will prevent parent-child relationships in the taxonomy.

Alternative Using Toolset Relationships:

For a more robust solution, consider creating a custom post type "Artist" and use a one-to-many relationship with the "Record" post type. This ensures each record has only one artist and avoids hierarchy issues.

Problem:

As a normal Administrator on a multisite instance, you are unable to create or modify Views, receiving a "You do not have permissions for that" error.

Solution:

The issue was resolved by adding the missing capability "toolset_edit_views" to the Administrator role.

You can use the Toolset Access plugin to add the capability to the user.

Problem:

A Toolset View on the page stopped working, showing only the shortcode. The legacy Toolset View editing options were unavailable, and the Toolset Blocks plugin was not active.

Solution:

- Go to WordPress Dashboard > Plugins > Add New > Commercial (tab).
- Click "Check for Updates."
- Ensure the Toolset Blocks plugin is installed and active.
