Help::success('title', 'message');
Help::info('title', 'message');
Help::warning('title', 'message');
Help::danger('title', 'message');

Headings template:

Both title and message are optional

Help::make('Only title');
Help::make()->message('Only message');

Messages can also be callable

Help::make()->message(function () {
    return "{$this->name} is awesome!";
});

Icons

You can pick one of the default SVG icons (http://www.zondicons.com/) provided by Steve Schoger.

Help::make('Title')->icon('help'); // the default one
Help::make('Title')->icon('info');
Help::make('Title')->icon('warning');
Help::make('Title')->icon('danger');
// Load a custom one
Help::make('Love you')
    ->message('Yes, I love you!')
    ->icon('<svg viewBox="0 0 20 20" xmlns="http://www.w3.org/2000/svg"><path d="m10 3.22-.61-.6a5.5 5.5 0 0 0 -7.78 7.77l8.39 8.39 8.39-8.4a5.5 5.5 0 0 0 -7.78-7.77z"/></svg>');
// or show no icon at all
Help::make('Sad')->withoutIcon();

Render html messages

Help::make('Title', 'Message with <a href="#">link</a>')->displayAsHtml();

From v0.2 the displayAsHtml() method applies also to the field name (unless shown as column header on index).

Full width on details screen

// Remove annoing padding in detail screen, also the default behaviour for the heading template 
Help::make('Negative margin')->showFullWidthOnDetail();

With side label

// Show a side label instead of the title on the top
Help::make('Look I\'m on the side')
    ->message('I\'m not...')
    ->withSideLabel();

Collapsible help fields

Help fields can be made collapsible using the fluent method collapsible(). Collapsible help fields are collapsed by default and toggle their state clicking on their title. Also, keep in mind that collapsible fields must define both a title and message and cannot be used with side labels.

// Collapsible field
Help::info('Click here to toggle', 'Lorem ipsum dolor sit amet...')
    ->collapsible();

Show help messages on index

/**
 * By default help messages aren't shown on index,
 * when enabled they are shown as an hoverable 
 * icon showing a plain (no html) tooltip.
 */
Help::make('Column title')
    ->message('Message with <a href="#">link</a>') // The link code will be stripped out on index
    ->alsoOnIndex();
    
// Field icons can be shown conditionally on index
Help::make()->message(function () {
    return $this->name?"{$this->name} is awesome!":null;
})->onlyOnIndex();
