alpha

This version is in early development and is subject to change and therefore not ready for wide use. There may be other stable versions available.

Dropdown github location npm version

A dropdown component that can be used in navigation menus.


Usage

Supports click trigger to open. User can select menu item or click outside menu to close it. When menu is open, outside clicks will be captured by menu.

Currently, usage intended with navigation menu.

Nunjucks syntax

Depending on your environment you'll want to use render or include. As a rule of thumb: server-side use include, precompiled browser use render. If you're using vf-eleventy you should use include.

Using include

You'll need to pass a context object from your code or Yaml file (example), as well as the path to the Nunjucks template. Nunjucks' include is an abstraction of render and provides some additional portability.


{% set context fromYourYamlFile %}
- or -
{% set context = {
  "component-type": "block",
  "label": "John doe",
  "width": "14rem",
  "labelAlign": "left",
  "menuItems": [
    {
      "text": "Profile",
      "link_href": "JavaScript:Void(0);"
    },
    {
      "text": "Settings",
      "link_href": "JavaScript:Void(0);"
    },
    {
      "text": "Logout",
      "link_href": "JavaScript:Void(0);"
    }
  ]
}
 %}
{% include "../path_to/vf-dropdown/vf-dropdown.njk" %}
                

Using render

This approach is best for bare-bones Nunjucks environments, such as precompiled templates with the Nunjucks slim runtime where include is not be available.

{% render '@vf-dropdown', {
  "component-type": "block",
  "label": "John doe",
  "width": "14rem",
  "labelAlign": "left",
  "menuItems": [
    {
      "text": "Profile",
      "link_href": "JavaScript:Void(0);"
    },
    {
      "text": "Settings",
      "link_href": "JavaScript:Void(0);"
    },
    {
      "text": "Logout",
      "link_href": "JavaScript:Void(0);"
    }
  ]
} %}
