Widget injection points

Every page (155) where a FeatherPanel plugin can inject a widget, the injection points it exposes and the full widgets.json schema.

Widgets let a plugin put its own HTML onto existing panel pages without patching the frontend. The panel renders each widget in an iframe (optionally wrapped in a card; add iframe.sandbox if you want a sandbox) at a named injection point on a page. For whole new pages in the sidebar, use Frontend/sidebar.json instead; see Frontend.

widgets.json

Put a JSON array in Frontend/widgets.json inside the plugin folder. component is a path below Frontend/Components/. This is from the DemoShowcase example plugin that ships with the panel:

[
  {
    "id": "demoshowcase-dashboard-card",
    "component": "demoshowcase/dist/dashboard-card.html",
    "enabled": true,
    "priority": 80,
    "page": "dashboard",
    "location": "after-header",
    "pluginName": "DemoShowcase",
    "title": "Demo Showcase",
    "description": "Example addon card widget",
    "size": "half",
    "card": { "enabled": true, "padding": "sm", "header": { "show": true } },
    "iframe": { "minHeight": "140px", "title": "Demo Showcase card" },
    "hidden": { "type": "plugin_setting", "key": "hide_admin_card", "equals": "true" }
  }
]

Widget fields

Visibility rules

enabled and hidden (also used by sidebar.json entries) accept a boolean or a rule object:

• { "type": "always" } and { "type": "never" }
• { "type": "plugin_setting", "key": "hide_x", "equals": "true" } compares one of the plugin's settings with equals (default "true"). An unset setting counts as no match.

Admins can also hide any single widget or sidebar entry from the plugin's settings page; that override wins over the manifest.
