The vf-form
manages a group of form inputs and interactive controls to collect data that can be sent to a server. The vf-form
is the wrapping component for all form elements.
Whenever you need to use a vf-form__item
and related input or control you need to wrap them with a vf-form
.
The vf-form
makes use of the vf-stack
layout component to evenly distrubute the form inputs on a page.
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
.
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" : "form",
"form_action" : "#",
"form_method" : "get",
"form_button_text" : "Submit",
}
%}
{% include "../path_to/vf-form/vf-form.njk" %}
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-form', {
"component-type" : "form",
"form_action" : "#",
"form_method" : "get",
"form_button_text" : "Submit",}
%}

This component is distributed with npm. After installing npm, you can install the vf-form
with this command. This will install all form items that work within a vf-form
too.
$ yarn add --dev @visual-framework/vf-form
The source files included are written in Sass(scss
). You can point your Sass include-path
at your node_modules
directory and import it like this.
@import "@visual-framework/vf-form/vf-form.scss";
Make sure you import Sass requirements along with the modules. You can use a project boilerplate or the vf-sass-starter
vf-form
so that it's cross linked to Form components. Tracking issuevf-form__core
as a thing and shows example of how to make a form.vf-form/vf-form.scss
requires __fieldset
and __legend
but they are missing from the package.json
File system location: components/vf-form
