Meta Box

Hello,

For the option group, it isn't possible. But you can try to set the sub-choices like this

function my_custom_callback() {
    return [
        [
            'value' => 'monkeys',
            'label' => 'Monkeys',
        ],
        [
            'value' => 'king_kong',
            'label' => 'King Kong',
            'parent' => 'monkeys',
        ],
        [
            'value' => 'curious_george',
            'label' => 'Curious George',
            'parent' => 'monkeys',
        ],
        [
            'value' => 'donkeys',
            'label' => 'Donkeys',
        ],
        [
            'value' => 'eeyore',
            'label' => 'Eeyore',
            'parent' => 'donkeys',
        ],
        [
            'value' => 'guss',
            'label' => 'Gus',
            'parent' => 'donkeys',
        ],
    ];
}

and set the setting flatten to false. Follow the documentation https://docs.metabox.io/fields/select/#settings

Hello,

I don't understand the question clearly. Can you please give me more details? Do you want to manage other CPTs by Meta Box CPT plugin?

Hello,

The function mb_get_block_field() only gets the field value when the block data is saved as attributes (default). If you save the data as post meta, you can use the helper function rwmb_meta(), for example:

WYSIWYG field: {{ mb.rwmb_meta( 'wysiwyg_field_id', '', post_id ) }}

Hello Matthew,

Sorry for the late reply. Let me answer your questions.

1. Yes, "hide from frontend" does not hide the field by JS code like MB Conditional Logic. It excludes the field from loading like MB Include Exclude does. Please read more in the documentation
https://docs.metabox.io/extensions/meta-box-include-exclude/
https://docs.metabox.io/extensions/meta-box-conditional-logic/

2, 3. The custom table created automatically in the builder uses data type TEXT for all columns to be compatible with most fields. Can you please share some screenshots of the field category_name and field group settings? Where do you add the shortcode on your site?

Hello,

WooCommerce has its own function to get attributes and it is complicated to do that in View (Twig code). You can create a custom function to get attributes with PHP code, return the value and call it in View for easier.
Refer to the documentation https://docs.metabox.io/extensions/mb-views/#running-php-functions

Hello,

Yes, it is possible. You can define a custom function in the file functions.php before adding the callback function in the MB builder. The choice should have the format: value => Label. For example:

function my_custom_callback() {
    return [
        'branda' => 'BrandA',
        'model1' => 'Model1',
        'model2' => 'Model2'
    ];
}

Hello,

Supporting a customization code for your specific needs is beyond our scope of support, please read more here https://support.metabox.io/topic/support-policy/

I think you can move the code that updates the group field value outside of the loop and recheck this issue. If you are not able to complete the task, please contact us here https://metabox.io/contact/
We offer a customization service with an extra fee.
