}Use this configuration on a page to get an laxar-headline-widget instance with a headline, an intro and a button on the right side of the headline.
If the button is pressed the widget publishes a takeActionRequest.doSomething event.
For full configuration options refer to the widget.json.
R1.1 The widget MUST display the configured headline text in a headline element. The configured text MUST be interpreted as internationalized HTML content.
R1.2 If no headline text is configured, the widget MUST NOT render a headline element.
R1.3 The headline level MUST be configurable. The level MUST be in the range from 1 to 6.
R2.1 The widget MUST display the configured intro text after the headline element. The configured text MUST be interpreted as internationalized HTML content.
R3.1 The widget MUST display configured buttons.
R3.2 The configured buttons MUST be set to the right of the headline and grouped and aligned to the right. Alternative enabled through configuration a button MUST be set to the left of the headline.
R3.3 The widget MUST display a default space between the buttons. The width of the space is defined by the theme.
R3.4 If the available space is not enough, the button group SHOULD be wrapped automatically. In every row each button group part SHOULD be aligned to the right.
R3.5 It MUST be possible to enable or disable each button by configuration.
R3.6 Each button text MUST be configurable. The configured text MUST be interpreted as internationalized HTML content. It MUST be possible to use icons as labels.
R3.7 For each button an access key MUST be configurable to allow the control by keyboard.

R3.10 The size of a button (mini, small, default, large) MUST be configurable.
R3.11 Each button MUST have a state (disabled, hidden, omitted or normal). The state of a button MUST depend on the page state (signaled with flags). If several flags are defined for a state, the state MUST be activated when one flag is at least true.
R3.12 In relation to the page state (signaled with flags, e.g. while a action is performed) a spinner SHOULD be displayed. In this case a CSS class is-busy MUST be set to allow to change the label with a spinner.
R3.13 Each button MUST have an unique page wide ID.
When a button or it's associated access key is pressed the widget MUST publish a takeActionRequest event with a key anchorDomElement with the ID of the button as value.
R3.14 The widget MUST add the CSS class ax-active to a button while the appropriate action is being processed.
R4.1 The widget MUST allow the configuration of a locale as described in the documentation to LaxarJS i18n. When displaying internationalized content, the widget MUST use the current language tag of the locale.
