An easy & complete Flexible Field for Laravel Nova, perfect for repeated and flexible field groups.
Here's a very condensed guide to get you started asap.

composer require whitecube/nova-flexible-content
A flexible field allows easy management of repeatable and orderable groups of fields. As opposed to the few existing solutions for Laravel Nova, this one does not have constraints on which fields you are allowed to use within these groups. That means you can use all Laravel Nova field types, and also any community-made fields.
A layout represents a group of fields that can be repeated inside the Flexible field. You can add as many different layouts as you wish. If only one layout is defined the field will behave like a simple Repeater and by adding more layouts you'll obtain a Flexible Content. Both concepts are similar to their cousins in Wordpress' ACF Plugin.
Layouts can be added using the following method on your Flexible fields:
addLayout(string $title, string $name, array $fields)The $name parameter is used to store the chosen layout in the field's value. Choose it wisely, you'll probably use it to identify the layouts in your application.
use Whitecube\NovaFlexibleContent\Flexible;
/**
* Get the fields displayed by the resource.
*
* @param \Illuminate\Http\Request $request
* @return array
*/
public function fields(Request $request)
{
return [
// ...
Flexible::make('Content')
->addLayout('Simple content section', 'wysiwyg', [
Text::make('Title'),
Markdown::make('Content')
])
->addLayout('Video section', 'video', [
Text::make('Title'),
Image::make('Video Thumbnail', 'thumbnail'),
Text::make('Video ID (YouTube)', 'video'),
Text::make('Video Caption', 'caption')
])
];
}
You can change the default "Add layout" button's text like so:
Flexible::make('Content')
->button('Add something amazing!');
Sometimes, addLayout definitions can get quite long, or maybe you want them to be shared with other Flexible fields. The answer to this is to extract your Layout into its own class. See the docs for more infomation on this.
In addition to reusable Layout classes, you can go a step further and create Preset classes for your Flexible fields. These allow you to reuse your whole Flexible field anywhere you want. They also make it easier to make your Flexible fields dynamic, for example if you want to add Layouts conditionally. And last but not least, they also have the added benefit of cleaning up your Nova Resource classes, if your Flexible field has a lot of addLayout definitions. See the docs for more infomation on this.
By default, the field takes advantage of a JSON column on your model's table. In some cases, you'd really like to use this field, but for some reason a JSON attribute is just not the way to go. For example, you could want to store the values in another table (meaning you'll be using the Flexible Content field instead of a traditional BelongsToMany or HasMany field). No worries, we've got you covered!
Tell the field how to store and retrieve its content by creating your own Resolver class, which basically just contains two simple methods: get and set. See the docs for more infomation on this.
