react-jsonschema-form-pagination

react-jsonschema-form-pagination

Features

• Separation of huge schemas into tabs
• Nested tabs - you can have any number of tabs nested inside your form
• Repeated fields - you can use the same field in multiple tabs, filling it only once
• Does not conflict with other extensions of Mozilla project

Installation

Install react-jsonschema-form-pagination by running:

npm install --s react-jsonschema-form-pagination

Usage

FormWithPagination is a wrapper for Mozilla's JSON Schema Form that allows a schema to be displayed into multiple Bootstrap tabs. This allows users to see a subset of the schema on each tab.

Use this project as you would use Mozilla's JSON Schema Form (see their documentation), but to leverage the tab features just provide these extra parameters:

• In the uiSchema object, use the new ui:tabID and ui:tabAliases property to associate each field with a tab
• Pass in an additional tabData array in props, if you want to customize tab naming

To show case use of the pagination project, we'll be using following schema as a base

const schema = {
  title: "A registration form",
  description: "A simple form example.",
  type: "object",
  properties: {
    firstName: { type: "string" },
    lastName: { type: "string" },
    age: { type: "integer" },
    phone: { type: "string" },
    nickName: { type: "string" }
  }
};

One level of tabs

Let's say we have only 1 level of tabs main and other. We can do it like this:

import applyPagination from "react-jsonschema-form-pagination";
import Form from "react-jsonschema-form";

const uiSchema = {
  firstName: {
    "ui:tabID": "main"
  },
  lastName: {
    "ui:tabID": "main"
  },
  age: {
    "ui:tabID": "main"
  },
  phone: {
    "ui:tabID": "main"
  },
  nickName: {
    "ui:tabID": "other"
  },
};

let FormWithPagination = applyPagination(Form);

render((
  <FormWithPagination
    schema={schema}
    uiSchema={uiSchema}
  />
), document.getElementById("app"));

When rendered this configuration will show 2 tabs

• main tab with firstName, lastName, age and phone fields
• other tab with nickName field

Multi tabs levels

Let's say we now want to have main tab divided in 2 more tabs general(lastName and age) and other ( with phone). This is how uiSchema should look like in order to do that :

const uiSchema = {
  firstName: {
    "ui:tabID": "main"
  },
  lastName: {
    "ui:tabID": [ "main", "general" ]
  },
  age: {
    "ui:tabID": [ "main", "general" ]
  },
  phone: {
    "ui:tabID": [ "main", "other" ]
  },
  nickName: {
    "ui:tabID": "other"
  }
};

When rendered this configuration will show 2 tabs

• main tab with firstName, and 2 sub tabs
  • general with lastName and age fields
  • other with phone field
• other tab with nickName field

Default level

When you don't specify ui:tabID, the field will be shown above the tabs.

For example, if we go back to single level example, but we want to always see firstName shown above the tab navigation. Here is how we can do this:

const uiSchema = {
  firstName: {},
  lastName: {
    "ui:tabID": "main"
  },
  age: {
    "ui:tabID": "main"
  },
  phone: {
    "ui:tabID": "main"
  },
  nickName: {
    "ui:tabID": "other"
  },
};

When rendered this configuration will show 2 tabs and firstName above the fields

• main tab with lastName, age and phone fields
• other tab with nickName field

Field aliases in different tabs

One of the requirements for this project was to support same field on different tabs, in order to do that you can specify field alias in uiSchema. Field alias is basically a field UI configuration, that will be used instead of original field in specified tab. Aliases can be nested as regular fields.

For example, if we want to show firstName in both tabs main and other.

const uiSchema = {
  firstName: {
    "ui:tabID": "main"
  },
  firsNameAlias: {
    "ui:tabID": "other"
  },
  lastName: {
    "ui:tabID": "main"
  },
  age: {
    "ui:tabID": "main"
  },
  phone: {
    "ui:tabID": "main"
  },
  nickName: {
    "ui:tabID": "other"
  },
  "ui:tabAlias": {
    firstName: "firsNameAlias"
  }
};

With this configuration pagination will put firstName in both main and other tabs.

ui:tabAlias is a simple object with

• keys - as original schema field names
• values - an alias name or an array of alias names

You can specify either single alias or as many aliases as you want with an array.

Configure tab names

Tab falls back to string name of the tab, but you can override it with tabData property
