40564: Added support for 'disabled' state for individual select options

[rybkinevg]

Description (*)

Added support for the disabled property on individual <option> elements within select form fields.

If the disabled key is set to true in the option array it renders the disabled="disabled" attribute accordingly.

Fixed Issues (if relevant)

1. Fixes [Feature] Support "disabled" state for individual select options in the admin config #40564

Manual testing scenarios (*)

№1 Modify the builtin source model:

Open the file: app/code/Magento/Config/Model/Config/Source/Yesno.php and modify the toOptionArray() method to add disabled property to the "No" option:

public function toOptionArray()
{
    return [['value' => 1, 'label' => __('Yes')], ['value' => 0, 'label' => __('No'), 'disabled' => true]];
}

№2 Clear Cache

№3 Navigate to admin configuration area

Go to Stores -> Configuration -> General -> Web, expand the Url Options section

№4 Verify the "Add Store Code to Urls" Field

Click on the dropdown to expand the options, the "No" option is disabled

Questions or comments

Current implementation treats all truthy values of the disabled property as the disabled state:

if ($option['disabled'] ?? false) {
    $html .= ' disabled="disabled"';
}

I am not sure, is this correct, or should we treat only explicitly true values as disabled state? For example:

if (isset($option['disabled']) && $option['disabled'] === true) {
    $html .= ' disabled="disabled"';
}
