how to use custom type in control

bindev

I want to know how to use the custom type in the Bagisto control.

@case('custom')
        <v-field {{ $attributes }}>
            {{ $slot }}
        </v-field>

Because when I make this

<x-shop::form.control-group.label class="mb-2 block text-[0.8125rem] max-sm:mb-1 required">Province</x-shop::form.control-group.label>
                            <x-shop::form.control-group.control
                                type="custom"
                                name="province_id"
                            >
                                {{-- <option value="" disabled>Select Province</option>
                                <option v-for="prov in provinces" :value="prov.id" :key="prov.id">
                                    @{{ prov.name }}
                                </option> --}}
                                <VSelect 
                                    ::option="provinces"
                                    v-model="province"
                                    name="province_id"
                                    class="form-control"
                                />
                            </x-shop::form.control-group.control>
                        <x-shop::form.control-group.error control-name="province" />

there is always an error.
