@justeat/f-form-field NPM

f-form-field

Fozzie Form Field Component.

Usage

Installation

Install the module using npm or Yarn:

yarn add @justeat/f-form-field

npm install @justeat/f-form-field

Vue Applications

You can import it in your Vue SFC like this (please note that styles have to be imported separately):

import FormField from '@justeat/f-form-field';
import '@justeat/f-form-field/dist/f-form-field.css';

export default {
    components: {
        FormField
    }
}

If you are using Webpack, you can import the component dynamically to separate the f-form-field bundle from the main bundle.client.js:

import '@justeat/f-form-field/dist/f-form-field.css';

export default {
    components: {
        // …
        FormField: () => import(/* webpackChunkName: "form-field" */ '@justeat/f-form-field')
    }
}

Each option can contain the following properties: `text` (required) - The text to be displayed.`value` (required) - The underlying value for the option.`disabled` (optional) - Can be used to prevent an option from being selected.`selected` (optional) - This will be ignored by `v-model` (see Vue docs on Form Input Bindings), but it may be used together with `disabled` to create a placeholder.

`hasError`	`Boolean`	`false`	When `true` border colour changes to red.
`inputType`	`String`	`text`	The type of input needed. Options: `text`, `email`, `password`, `radio`, `checkbox`, `dropdown`, `number`, `tel`, `textarea`
