Page layouts and panels

Pages are divided into three panels:

The static panel is the primary context of the page. All standard application pages use it automatically.
The dynamic panel (optional) is for displaying detailed information in the context of the static panel. Individual features mount Vue applications into it to display contextual content.
The AI panel (collapsible) is for intelligent features.

See the Design System documentation for more information about page structure.

Within the static panel, the index and detail layout components provide consistent spacing and structure for the page heading, alerts, and content areas.

Panels

Static panel

The Layouts::StaticPanelComponent ViewComponent wraps the main content area. All standard application pages use it automatically. You don't need to adopt it explicitly when building a new page.

Dynamic panel

The DynamicPanel Vue component defines the structure of dynamic panel, including its header, actions and content areas. Use it as the direct child of MountingPortal, with the mount-to="#contextual-panel-portal" and append props.

Props:

Prop	Type	Default	Description
`header`	`String`	`null`	Header text. The `header` slot takes precedence when provided.
`maximizeUrl`	`String`	`null`	When set, a maximize button is rendered that links to this URL.

Slots:

Slot	Description
Default	Main panel body content.
`header`	Custom header markup. Takes precedence over the `header` prop.
`actions`	Panel header actions. For more information, see Panel actions.

Events:

Event	Payload	Description
`close`	None	Emitted when the close button is clicked.
`maximize`	`MouseEvent`	Emitted when the maximize button is clicked.

Example:

<script>
import DynamicPanel from '~/vue_shared/components/dynamic_panel.vue';

export default {
  components: { DynamicPanel },
  methods: {
    onClose() {
      // handle close
    },
  },
};
</script>

<template>
  <mounting-portal mount-to="#contextual-panel-portal" append>
    <dynamic-panel header="Example" @close="onClose">
      <!-- Content goes here -->
    </dynamic-panel>
  </mounting-portal>
</template>

With a custom header, maximize button, and actions:

<template>
  <mounting-portal mount-to="#contextual-panel-portal" append>
    <dynamic-panel :maximize-url="fullUrlToEntity" @close="onClose" @maximize="onMaximize">
      <template #header>
        <span class="panel-header-inner-text">{{ entityName }}</span>
      </template>

      <template #actions>
        <gl-button
          v-gl-tooltip.bottom="__('Example action')"
          category="tertiary"
          icon="remove"
          size="small"
          :aria-label="__('Example action')"
          @click="onAction"
        />
      </template>

      <!-- Content goes here -->
    </dynamic-panel>
  </mounting-portal>
</template>

Panel actions

Panel actions are icon buttons rendered in the panel header, to the left of the built-in close and maximize buttons.

Three approaches are available depending on your context:

1. Dynamic panel actions slot

Use this when your component is a direct consumer of DynamicPanel:

<template>
  <dynamic-panel header="Details" @close="onClose">
    <template #actions>
      <gl-button
        v-gl-tooltip.bottom="$options.i18n.editLabel"
        category="tertiary"
        icon="pencil"
        size="small"
        :aria-label="$options.i18n.editLabel"
        @click="onEdit"
      />
    </template>
    <detail-view />
  </dynamic-panel>
</template>

2. Static panel static_panel_actions content region (HAML)

Use this from the HAML view file when rendering actions in the static panel:

- content_for :static_panel_actions do
  = link_button_to _("Example action"), path_to_action, category: :tertiary, size: :small

If the actions are not simple links, consider using PanelActionsPortal instead.

3. PanelActionsPortal Vue component

Use PanelActionsPortal when one or more of the following are true:

The actions to render in the static panel are not simple links, and require client side behavior, for example, buttons or dropdowns.
The actions are defined deep in the component tree, making it impractical to pass them to the actions slot of DynamicPanel.
The application renders in both the static and dynamic panels, for example, work items.

<script>
import PanelActionsPortal from '~/vue_shared/components/panel_actions_portal.vue';

export default {
  components: { PanelActionsPortal },
};
</script>

<template>
  <panel-actions-portal>
    <gl-button category="tertiary" size="small" @click="onAction">
      {{ __('Example action') }}
    </gl-button>
  </panel-actions-portal>
</template>

Import path: ~/vue_shared/components/panel_actions_portal.vue.

Panel actions guidance

Follow these rules when adding buttons to a panel actions area:

Use only buttons (or links that look like buttons), for example:
- GlButton (Vue)
- GlDisclosureDropdown (Vue)
- Pajamas::ButtonComponent (HAML/Ruby)
- link_button_to (HAML/Ruby)
Buttons should have category="tertiary" and size="small".
Icon only buttons must:
- have a tooltip which appears below the button (v-gl-tooltip.bottom="...")
- set aria-label set to the same string as the tooltip.
If you have four or more actions, group the less commonly used ones in a "More actions" icon-only dropdown using the ellipsis_h icon, with no-caret, category="tertiary", and size="small" options as well.
Ensure the page's entry template sets @force_show_panel_header = true. For example, see app/views/groups/observability/show.html.haml#L2. This ensures the static panel's header is always rendered, no matter the value of the page_breadcrumbs_in_top_bar feature flag.

Example with a "More actions" dropdown:

<template>
  <dynamic-panel header="Details" @close="onClose">
    <template #actions>
      <gl-button
        v-gl-tooltip.bottom="__('Edit')"
        category="tertiary"
        icon="pencil"
        size="small"
        :aria-label="__('Edit')"
        @click="onEdit"
      />
      <gl-disclosure-dropdown
        v-gl-tooltip.bottom="__('More actions')"
        icon="ellipsis_h"
        category="tertiary"
        size="small"
        no-caret
        :toggle-aria-label="__('More actions')"
        :items="moreActions"
      />
    </template>
    <detail-view />
  </dynamic-panel>
</template>

Layouts

Layout components provide consistent spacing and structure within the content area of a panel. Both ViewComponent and Vue component equivalents are available.

Index layout

Use the index layout for pages that list entities. It provides consistent structure for the page heading, alerts, and main content area.

Parameters:

See Index layout.

Slots:

See Index layout.

HAML (`Layouts::IndexLayout`)

Example:

= render ::Layouts::IndexLayout.new(heading: _('Tokens'), description: _('Manage your tokens.')) do |c|
  - c.with_alerts do
    = render Pajamas::AlertComponent.new(variant: :danger, title: _('Failed to create token.'))
  = render 'tokens_table'

For more information, see Index layout.

Vue (`IndexLayout`)

Props:

Prop	Type	Default	Description
`heading`	`String`	`null`	Page title text.
`headingTag`	`String`	`null`	Heading element tag: `'h1'` or `'h2'`. Defaults to the tag provided by context.
`description`	`String`	`null`	Page description text.
`loading`	`Boolean`	`false`	When `true`, renders a loading icon in place of the content.
`pageHeadingSrOnly`	`Boolean`	`false`	When `true`, visually hides the page heading.

Slots:

Slot	Description
`before`	Content rendered before the page heading.
`heading-wrapper`	Replaces the heading element entirely.
`heading`	Custom heading markup.
`description`	Custom description markup.
`alerts`	Page alerts. Rendered only when the slot is provided.
`loading`	Custom loading state. Falls back to `GlLoadingIcon` when not provided.
Default	Main page content.

Example:

<script>
import IndexLayout from '~/vue_shared/components/index_layout.vue';

export default {
  components: { IndexLayout },
};
</script>

<template>
  <index-layout :heading="$options.i18n.heading" :description="$options.i18n.description">
    <template v-if="hasAlerts" #alerts>
      <gl-alert v-if="error" variant="danger" @dismiss="onDismissError">
        {{ errorMessage }}
      </gl-alert>
    </template>

    <tokens-table :tokens="tokens" />
  </index-layout>
</template>

Detail layout

Use the detail layout for detail or show pages. It extends the index layout with a sidebar slot.

HAML (`Layouts::DetailLayout`)

Parameters:

See Detail layout.

Slots:

Same as Detail layout, plus:

Slot	Description
`sidebar`	Sidebar content.

Example:

= render ::Layouts::DetailLayout.new(heading: _('Page title'), description: _('Page description')) do |c|
  - c.with_alerts do
    = render Pajamas::AlertComponent.new(title: 'Alert message')
  - c.with_sidebar do
    = render 'sidebar'

  = render 'items_table'

For more information, see Detail layout.

Vue (`DetailLayout`)

Props:

Same as IndexLayout (see Index layout).

Slots:

Same as IndexLayout, plus:

Slot	Description
`sidebar`	Sidebar content.

Example:

<script>
import DetailLayout from '~/vue_shared/components/detail_layout.vue';

export default {
  components: { DetailLayout },
};
</script>

<template>
  <detail-layout :heading="token.name">
    <template #sidebar>
      <token-metadata :token="token" />
    </template>

    <token-body :token="token" />
  </detail-layout>
</template>
