Hi!
When using Taxonomy field (https://docs.metabox.io/fields/taxonomy/), is it possible to hide some of the term that I don't want to use?

For example:
I have a taxonomy with term A, B, C, D, E.
I create a Taxonomy Field as a Checkbox List. I would like to show only the A, B, and C term when editting, the term D, and E will be hidded.

Thank you!

Hi,

Yes, it is possible. You can exclude an array of term IDs with the field setting query_args. Please read more on the documentation

Hi. Thank you for your reply but I dind't mean that.

The links you shared are for front end, using the query_args.

I was asking for the back end, when using a Taxonomy Field of Meta Box, the editors/writers can see and choose only the term A, B, C, not all terms of a taxonomy.

Hi,

The link with instruction is applied to the taxonomy field in the backend. Please try to use this one
```
function your_prefix_function_name( $meta_boxes ) {
    $meta_boxes[] = [
        'title'  => __( 'My Meta Box', 'your-text-domain' ),
        'id'     => 'my-meta-box',
        'fields' => [
            [
                'name'       => __( 'Taxonomy', 'your-text-domain' ),
                'id'         => 'taxonomy_ipppnv41eid',
                'type'       => 'taxonomy',
                'taxonomy'   => ['category'],
                'field_type' => 'select_advanced',
                'query_args' => [
                    'exclude' => 86, // here or use array of term IDs [86, 87, 88]
                ],
            ],
        ],
    ];
    return $meta_boxes;
}
```

Many thanks for your reply. It works!

I'm using the AIO plugin so I just need to put the 'exclude'/'include' into the Query args setting.

But there is another issue: If I have more than 1 Taxonomy field assigning to the same taxonomy, only the last one saves data when updating the post.

As I have a taxonomy named Characteristic with terms for hair colors, eyes color, ethnicity,... I want to put them into different Taxonomy fields (Hair, Eyes, Ethnicity for example. 3 of them are assigned to Characteristic taxonomy) to make it easy when editing the posts.

I could create multiple new taxonomies for each of the groups but there are only 2 or 3 options for 1 group, making it too many taxonomies to manage.
