Control Panel Templates

The control panel is built using Twig templates, so extending it with new pages should feel familiar if you’ve worked with Twig on the front end.

Plugins can define templates within the templates/ folder within their base source folder. Templates within there can be referenced using the plugin’s handle as the template path prefix.

For example if a plugin’s handle is foo and it has a templates/bar.twig template, that template could be accessed by going to /admin/foo/bar, or from Twig by including/extending foo/bar (or foo/bar.twig).

Modules can have templates too, but they will need to manually define a template root before they are accessible.

# Page Templates

To add a new full page to the control panel, create a template that extends the _layouts/cp.twig (opens new window) template.

At a minimum, your template should set a title variable and define a content block:

{% extends "_layouts/cp.twig" %}
{% set title = "Page Title"|t('plugin-handle') %}

{% block content %}
  <p>Page content goes here</p>
{% endblock %}

# Supported Variables

The following variables are supported by the _layouts/cp.twig template:

Variable	Description
`title`	The page title.
`bodyClass`	An array of class names that should be added to the `<body>` tag.
`fullPageForm`	Whether the entire page should be wrapped in one big `<form>` element (see Form Pages).
`crumbs`	An array of breadcrumbs (see Adding Breadcrumbs).
`tabs`	An array of tabs (see Adding Tabs).
`selectedTab`	The ID of the selected tab.
`showHeader`	Whether the page header should be shown (`true` by default).
`mainAttributes`	A hash of HTML attributes that should be added to the `<main>` tag.

# Available Blocks

The _layouts/cp template defines the following blocks, which your template can extend:

Block	Outputs
`actionButton`	The primary Save button.
`content`	The page’s main content.
`contextMenu`	An optional context menus beside the page title (e.g. the revision menu on Edit Entry pages).
`details`	The page’s right sidebar content.
`footer`	The page’s footer content.
`header`	The page’s header content, including the page title and other header elements.
`pageTitle`	The page title (rendered within the `header` block).
`sidebar`	The page’s left sidebar content.
`toolbar`	The page’s toolbar content.

# Adding Breadcrumbs

To add breadcrumbs to your page, define a crumbs variable, set to an array of the breadcrumbs.

Each breadcrumb should be represented as a hash with the following keys:

Key	Description
`label`	The breadcrumb label.
`url`	The URL that the breadcrumb should link to.

For example, the following crumbs array defines two breadcrumbs:

{% set crumbs = [
  {
    label: 'Plugin Name'|t('plugin-handle'),
    url: url('plugin-handle'),
  },
  {
    label: 'Products'|t('plugin-handle'),
    url: url('plugin-handle/products'),
  },
] %}

# Adding Tabs

To add tabs to your page, define a tabs variable, set to a hash of the tabs, indexed by tab IDs.

Each tab should be represented as a nested hash with the following keys:

Key	Description
`label`	The tab label.
`url`	The URL or anchor that the tab should link to.
`class`	A class name that should be added to the tab (in addition to `tab`).

For example, the following tabs hash defines two tabs, which will toggle the hidden class of <div> elements whose IDs match the anchors:

{% set tabs = {
  content: {
    label: 'Content'|t('plugin-handle'),
    url: '#content',
  },
  settings: {
    label: 'Settings'|t('plugin-handle'),
    url: '#settings',
  },
} %}

The first tab will be selected by default. You can force a different tab to be selected by default by setting a selectedTab variable to the ID of the desired tab:

{% set selectedTab = 'settings' %}

# Form Pages

If the purpose of your template is to present a form to the user, start by setting the fullPageForm variable to true at the top:

{% set fullPageForm = true %}

When you do that, everything inside the page’s <main> element will be wrapped in a <form> element, and a Save button and CSRF input will be added to the page automatically for you. It will be up to you to define the action input, however.

{% block content %}
  {{ actionInput('plugin-handle/controller/action') }}
  <!-- ... -->
{% endblock %}

Your template can also define the following variables, to customize the form behavior:

Variable	Description
`formActions`	An array of available Save menu actions for the form (see Alternate Form Actions).
`mainFormAttributes`	A hash of HTML attributes that should be added to the `<form>` tag.
`retainScrollOnSaveShortcut`	Whether the page’s scroll position should be retained on the subsequent page load when the `Ctrl`/`Command` + `S` keyboard shortcut is used.
`saveShortcutRedirect`	The URL that the page should be redirected to when the `Ctrl`/`Command` + `S` keyboard shortcut is used.
`saveShortcut`	Whether the page should support a `Ctrl`/`Command` + `S` keyboard shortcut (`true` by default).

# Form Inputs

Craft’s _includes/forms.twig (opens new window) template defines several macros that can be used to display your form elements.

Most input types have two macros: one for outputting just the input; and another for outputting the input as a “field”, complete with a label, author instructions, etc.

For example, if you just want to output a date input, but nothing else, you could use the date macro:

{% import '_includes/forms.twig' as forms %}

{{ forms.date({
  id: 'start-date',
  name: 'startDate',
  value: event.startDate,
}) }}

However if you want to wrap the input with a label, author instructions, a “Required” indicator, and any validation errors, you could use the dateField macro instead:

{% import '_includes/forms.twig' as forms %}

{{ forms.dateField({
  label: 'Start Date'|t('plugin-handle'),
  instructions: 'The start date of the event.'|t('plugin-handle'),
  id: 'start-date',
  name: 'startDate',
  value: event.startDate,
  required: true,
  errors: event.getErrors('startDate'),
}) }}

# Alternate Form Actions

If you want your form to have a menu button beside the Save button with alternate form actions, define a formActions variable, set to an array of the actions.

Each action should be represented as a hash with the following keys:

Key	Description
`action`	The controller action path that the form should submit to, if this action is selected.
`confirm`	A confirmation message that should be presented to the user when the action is selected, before the form is submitted.
`data`	A hash of any data that should be passed to the form’s `submit` event.
`destructive`	Whether the action should be considered destructive, which will cause it to be listed in red text at the bottom of the menu, after a horizontal rule.
`label`	The action’s menu option label.
`params`	A hash of additional form parameters that should be included in the submission if the action is selected.
`redirect`	The URL that the controller action should redirect to if successful.
`retainScroll`	Whether the page’s scroll position should be retained on the subsequent page load.
`shift`	Whether the action’s keyboard shortcut should include the `Shift` key.
`shortcut`	Whether the action should be triggered by a keyboard shortcut.

For example, the following formActions array defines three alternative form actions:

{% set formActions = [
  {
    label: 'Save and continue editing'|t('plugin-handle'),
    redirect: 'plugin-handle/edit/{id}',
    retainScroll: true,
    shortcut: true,
  },
  {
    label: 'Save and add another'|t('plugin-handle'),
    redirect: 'plugin-handle/new',
    shortcut: true,
    shift: true,
  },
  {
    label: 'Delete'|t('plugin-handle'),
    confirm: 'Are you sure you want to delete this?'|t('plugin-handle'),
    redirect: 'plugin-handle',
    destructive: true,
  },
] %}

Note that when formActions is defined, the saveShortcut, saveShortcutRedirect, and retainScrollOnSaveShortcut variables will be ignored, as it will be up to the individual form actions to define that behavior.
