ska-blocks -> Options -> Dynamic content option allows you to set up commonly used data so that it can be kept all in once place. You can set an e-mail, phone, social media addresses or other custom data:

The values can then be referred to on other pages using [ska-*]
shortcodes or, for links, using the Dynamic links interface:

The dynamic links interface will appear on the block toolbar when using Element or Text blocks with the HTML tag name <a>
.
Not to be confused with another “link” item on the toolbar that is used for adding a link to Rich Text (as in it will not add a link to the block’s root element, but will wrap some part of the text inside the block in an additional <a>
element which is not valid HTML):

Dynamic content options
All the options have additional settings:


Widget
Enabling the “Widget” setting of a dynamic option will display it on the WordPress admin dashboard so that it can be conveniently edited.

The widget will be visible to all users with the unfiltered_html
capability.
Type
Textarea
The content type option can be changed to “Textarea” for a bigger input in the widget.
Toggle
When using the “Toggle” type the value is considered “On” when there is any text and “Off” when there is no text.

In the widget only a checkbox is shown.

This can be used in combination with the Condition block and some code to provide a simple toggle for some content.
function ska_condition_campaign_active() {
$shortcodes = ska_blocks()->get('options')->get('dynamicShortcodes');
return isset($shortcodes['campaign-active']) && !empty($shortcodes['campaign-active']);
}
