+## How it works
+
+Moodle action menus are a reusable component that can display a list of actions in a dropdown menu. They are used in many places in Moodle, including the user menu, the course administration menu, and the activity administration menu.
+
+## Source files
+
+- `lib/outputcomponents.php`: contains the main `action_menu`, `action_menu_link` and `pix_icon`.
+- `lib/classes/output/local/action_menu/subpanel.php`: contains the `subpanel` menu item class.
+- `lib/templates/action_menu.mustache`: contains the main template for the action menu.
+- `lib/templates/action_menu_*`: location for the legacy auxliar mustache files.
+- `lib/templates/local/action_menu/*`: location for any new auxiliar mustache files.

+
+## Usage
+
+### Rendering an action menu
+
+The component output classes can render an action menu entirely in PHP. The steps to do it are:
+
+1. Create an action menu instance (with or without items)
+2. (optional) Setup the action menu trigger
+3. (optional) Add items to the menu (if they are not added on creation)
+4. Render the menu.
+
+The following code is a basic example of an action menu:
+
+{{< php >}}
+/** @var core_renderer $output*/
+$output = $PAGE->get_renderer('core');
+
+$menu = new action_menu();
+
+// Add items.
+$menu->add(new action_menu_link(
+    new moodle_url($PAGE->url, ['foo' => 'bar']),
+    new pix_icon('t/emptystar', ''),
+    'Action link example',
+    false
+));
+
+echo $output->render($menu);
+{{< / php >}}
+
+And this is the same example but passing the items in the creation:
+
+{{< php >}}
+/** @var core_renderer $output*/
+$output = $PAGE->get_renderer('core');
+
+$menu = new action_menu([
+    new action_menu_link(
+        new moodle_url($PAGE->url, ['foo' => 'bar']),
+        new pix_icon('t/emptystar', ''),
+        'Action link example',
+        false
+    ),
+]);
+
+echo $output->render($menu);
+{{< / php >}}
+
+### Setup the menu trigger
+
+By default, the action menu trigger is a cog icon. However, the class has methods to convert it to a kebab menu or even display any arbitrary content.
+
+Example of a kebab menu:
+
+{{< php >}}
+/** @var core_renderer $output*/
+$output = $PAGE->get_renderer('core');
+
+$menu = new action_menu();
+$menu->set_kebab_trigger(get_string('edit'), $output);
+$menu->set_additional_classes('fields-actions');
+{{< / php >}}
+
+Example of a custom trigger:
+
+{{< php >}}
+/** @var core_renderer $output*/
+$output = $PAGE->get_renderer('core');
+
+$menu = new action_menu();
+$menu->set_menu_trigger(get_string('edit'));
+{{< / php >}}
+
+### Add items
+
+Items can be added as an array on creation or using the `add` method. Depending on the param passed to `add` the item can be displayed in two different locations:
+
+Primary items: are displayed next to the trigger button as direct actions.
+Secondary items: are displayed inside the action menu dropdown.
+
+The item location must be configured before adding the element. The following example shows different ways to add primary and secondary menu items.
+
+{{< php >}}
+// Primary items examples.
+$menu->add(new action_menu_link(
+    new moodle_url($PAGE->url),
+    new pix_icon('t/emptystar', ''),
+    'Action link example',
+    true
+));
+$menu->add(new action_menu_link_primary(
+    $PAGE->url,
+    new pix_icon('t/emptystar', ''),
+    'Action link example',
+));
+
+// Secondary items examples.
+$menu->add(new action_menu_link(
+    new moodle_url($PAGE->url),
+    new pix_icon('t/emptystar', ''),
+    'Action link example',
+    false
+));
+$menu->add(new action_menu_link_secondary(
+    $PAGE->url,
+    new pix_icon('t/user', ''),
+    'Action link example',
+));
+{{< / php >}}
+
+## Types of items
+
+The `add` method accepts several item types.
+
+### `action_menu_link`
+
+The `action_menu_link` class is the generic class for link items. It has several construct params:
+
+- `moodle_url $url`: the link URL.
+- `pix_icon $icon`: an optional pix_icon. If none passed, the item will show the trigger icon or none if it is a kebab menu.
+- `string $text`: the text to display.
+- `bool $primary`: if the item is primary or secondary. By default, all items are primary.
+- `array $attributes`: an optional array of HTML attributes.
+
+Two convenience classes extend `action_menu_link`:
+
+- `action_menu_link_primary`: will be added as a primary item.
+- `action_menu_link_secondary`: will be added as a secondary item.
+
+### `pix_icon`
+
+The action menu can render `pix_icon` as primary actions. The `pix_icon` is a standard output class for generating icons in Moodle.
+
+Construct params:
+
+- `String $pix`: the internal icon location. For example, "t/user".
+- `String $alt`: an optional alternative text
+- `String $component`: the pix icon component. By default, only core icons from the `pix` folder will be used
+- `Array $attributes`: optional HTML attributes.
+
+### `core\output\local\action_menu\subpanel`
+
+The `core\output\local\action_menu` allow the `action_menu` to add items that display subpanels when hovered or clicked.
+
+Construct params:
+
+- `string $text`: text to display in the menu item
+- `renderable $subpanel`: the output to render inside the subpanel. This param should be renderable using the standard `output::render` method.
+- `array $attributes` optional HTML attributes
+
+The following example creates a subpanel using a renderable choicelist instance:
+
+{{< php >}}
+/** @var core_renderer $output*/
+$output = $PAGE->get_renderer('core');
+
+// A choice list is a renderable class to outpout a user choice.
+$choice = new core\output\choicelist('Choice example');
+$choice->add_option("statusa", "Status A", [
+    'url' => $PAGE->url,
+    'description' => 'Status A description',
+    'icon' => new pix_icon('t/user', '', ''),
+]);
+$choice->add_option("statusb", "Status B", [
+    'url' => $PAGE->url,
+    'description' => 'Status B description',
+    'icon' => new pix_icon('t/groupv', '', ''),
+]);
+$choice->set_selected_value('statusb');
+
+$menu = new action_menu();
+
+// Add subpanel item.
+$menu->add(new core\output\local\action_menu\subpanel(
+    'Subpanel example',
+    $choice
+));
+
+echo $output->render($menu);
+{{< / php >}}
+
+### HTML string
+
+If a plain string is added to an action_menu, the action_menu::add method will be printed as it is inside the dropdown menu (as a secondary item).
