Installation

$ npm install react-dyn-tabs --save

or

$ yarn add react-dyn-tabs

Basic Example

import React from 'react';
import 'react-dyn-tabs/style/react-dyn-tabs.css';
import 'react-dyn-tabs/themes/react-dyn-tabs-card.css';
import useDynTabs from 'react-dyn-tabs';

export default () => {
  const options = {
    tabs: [
      {
        id: '1',
        title: 'tab 1',
        panelComponent: (porps) => <p> panel 1 </p>,
      },
      {
        id: '2',
        title: 'tab 2',
        panelComponent: (porps) => <p> panel 2 </p>,
      },
    ],
    selectedTabID: '1',
  };
  const [TabList, PanelList] = useDynTabs(options);
  return (
    <>
      <TabList></TabList>
      <PanelList></PanelList>
    </>
  );
};

Simple manipulation

import React from 'react';
import 'react-dyn-tabs/style/scss/react-dyn-tabs.scss';
import 'react-dyn-tabs/themes/scss/react-dyn-tabs-card.scss';
import useDynTabs from 'react-dyn-tabs';

export default () => {
  const options = {
    tabs: [
      {
        id: '1',
        title: 'tab1',
        panelComponent: (porps) => <p> panel 1 </p>,
      },
      {
        id: '2',
        title: 'tab2',
        panelComponent: (porps) => <p> panel 2 </p>,
      },
    ],
    selectedTabID: '1',
  };
  let _instance;
  const [TabList, PanelList, ready] = useDynTabs(options);
  ready((instance) => {
    _instance = instance;
  });
  const addTab3 = function () {
    // open tab 3
    _instance.open({id: '3', title: 'Tab 3', panelComponent: (porps) => <p> panel 3 </p>}).then(() => {
      console.log('tab 3 is open');
    });
    // switch to tab 3
    _instance.select('3').then(() => {
      console.log('tab 3 is selected');
    });
  };
  return (
    <>
      <button onClick={addTab3}>Add tab 3</button>
      <TabList></TabList>
      <PanelList></PanelList>
    </>
  );
};

NOTE :

• Tabs can't be manipulated safely before the first render, use ready() to make a function available after the component is mounted.

• ready function and instance Object will not be changed after re-rendering multiple times.

• id: String

Example

const result = instance.isSelected('Your tab ID');

select

Makes current and previous selected tab to be re-rendered

Triggers 'onInit', 'onChange' and 'onSelect' event.

Selecting an already selected tab only triggers 'onInit' event.

Return value : Promise

Parameters:

• id: string

Example

if (instance.isSelected('1') == false) {
  instance.select('1').then(({currentData, instance}) => {
    console.log('tab 1 is selected');
  });
}

close

Triggers 'onInit', 'onChange' and 'onClose' event.

Closing an already closed tab only triggers 'onInit' event.

It switches to the previously selected tab before closing if switching parameter was true and tab was already opened and selected.

Return value : Promise

Parameters:

• id: string
• switching: boolean (default : true)

Makes all tabs to be re-rendered.

triggers onInit event.

Return value : Promise

Example

instance.refresh().then(({currentData, instance}) => {});

getOption

Parameters:

• optionName : String

Example

const direction = instance.getOption('direction');
const onSelect = instance.getOption('onSelect');

setOption

You can use this method for setting all options except selectedTabID and tabs options.

For re-rendering immediately after this function, you should call refresh method after it.

Return value : instance object

Parameters:

• optionName : String
• optionValue : string|boolean|object|function

Example

instance.setOption('direction', 'rtl');
instance.setOption('onSelect', () => {});
instance.setOption('beforeSelect', () => false);

console.log(tabData.id); // 3

setTab

set tabData by id. for re-rendering immediately after this function, you should call refresh method after it.

Return value : instance

Parameters:

• tab id : String
• source object : containing the properties you want to apply

Example

instance.setTab('home', {disable: true});
instance.setTab('contact', {closable: false, panelComponent: (props) => <p>contact panel</p>});

on

Attach an event handler function for one event.

Return value : instance

Parameters:

• event Name : String (can be either of onSelect|onClose|onOpen|onInit|onChange|onDestroy)
• handler : function

Example

const handler = React.useCallback(function (params) {
  const {currentSelectedTabId, previousSelectedTabId} = params;
}, []);
instance.on('onSelect', handler);

one

Attach a handler to an event. The handler is executed at most once.

const deattachHandler = () => {
  instance.off('onSelect', handler);
};

getData

get a copy of data

Return value : Object

Example

const {selectedTabID, openTabIDs} = instance.getData();

NOTE :

• getCopyData function is an older version of getData function and it is enabled by default so that existing users do not have to change their code. You are free to use both conventions.

getPreviousData

get a copy of data in previous render

Return value : Object

Example

const {selectedTabID, openTabIDs} = instance.getPreviousData();

NOTE :

• getCopyPerviousData function is an older version of getPreviousData function and it is enabled by default so that existing users do not have to change their code. You are free to use both conventions.

tabData

property name	type	default value	required
id	string		false
title	string	' '	false
tooltip	string	' '	false
panelComponent	React Element | React Component | null	A function component which returns empty div	false

const tabData = {
  id: 'contactID',
  title: 'contactTitle',
  tooltip: 'contactTooltip',
  disable: true,
  iconClass: 'fa fa-home',
  closable: false,
  panelComponent: (porps) => <p> contact content </p>,

// or
if (instance.isOpen(tabData.id) == false) {
  instance.open(tabData).then(() => {});
}

Lazy Loading

Styling

react-dyn-tabs does not include any style loading by default. Default stylesheets and themes are provided and can be included in your application if desired.

import 'react-dyn-tabs/style/react-dyn-tabs.min.css';
// or import 'react-dyn-tabs/style/scss/react-dyn-tabs.scss';
import 'react-dyn-tabs/themes/react-dyn-tabs-card.min.css';
// or import 'react-dyn-tabs/themes/scss/react-dyn-tabs-card.scss';

NOTE :

You can find other themes at themes folder.

Caveats

• Some actions like open, select, close and refresh cause re-rendering, and using them immediately after calling useDynTabs hook will create an infinite loop and other bugs that most likely you don't want to cause. you should use them inside event listeners or subscriptions.

• Do not use setState inside the onInit callback because it leads to an infinite loop.

Deprecated features

These deprecated features can still be used, but should be used with caution because they are expected to be removed entirely sometime in the future. You should work to remove their use from your code.

• Third element of returned array by useDynTabs hook should not be used as an object, it is no longer recommended and only be kept for backwards compatibility purposes, may be removed in the future. Avoid using it as an object and use the code below instead of it.

const [TabList, PanelList, ready] = useDynTabs(options);
const open_tab_3 = function () {
  ready(function (instance) {
    if (instance.isOpen('3') === false) {
      instance.open({id: '3', title: 'mock tab 3'});
      instance.select('3');
    }
  });
};

• First parameter of onSelect function is an object and has perviousSelectedTabId property which is deprecated. you should use previousSelectedTabId property instead of perviousSelectedTabId property.

• First parameter of onChange function is an object and has perviousData property which is deprecated. you should use previousData property instead of perviousData property.
