Select Unpacked

@formField('select', [
    'name' => 'discipline',
    'label' => 'Discipline',
    'unpack' => true,
    'options' => [
        [
            'value' => 'arts',
            'label' => 'Arts & Culture'
        ],
        [
            'value' => 'finance',
            'label' => 'Banking & Finance'
        ],
        [
            'value' => 'civic',
            'label' => 'Civic & Public'
        ],
        [
            'value' => 'design',
            'label' => 'Design & Architecture'
        ],
        [
            'value' => 'education',
            'label' => 'Education'
        ],
        [
            'value' => 'entertainment',
            'label' => 'Entertainment'
        ],
    ]
])

A migration to save the above select field would be:

Schema::table('posts', function (Blueprint $table) {
    ...
    $table->string('discipline')->nullable();
    ...
});

When used in a block, no migration is needed.
