react-kfc-menu

A react menu that inspired by KFC menu and functions like it. this package works in conjunction with react-tabs-scrollable , so in order to use this package you have to install react-tabs-scrollable to use its tabs in the menu.

I took the idea while I was exlporing the KFC menu on their website and I liked the idea and I thought it's practical and simple and it can be used on restaurants and cafes menu.

Install

npm install --save react-kfc-menu
yarn add react-kfc-menu

How it works

I'm using a fixed indicator div inside the blocks' container so I can indicate if a block is overlaping the indicator so I can determine where in the page is the selected block located passed on that indicator. When you click on a tab the page will scroll to that indicator position + the current position of that block.

Usage

import React from "react";
import { Tabs, Tab } from "react-tabs-scrollable";
import { Menu, MenuBlock } from "react-kfc-menu";
import "react-tabs-scrollable/dist/rts.css";

function App() {
  const [activeTab, setActiveTab] = React.useState(10);

  // define a onClick function to bind the value on tab click
  const menuRef = useRef < any > null;
  const onTabClick = (e, index) => {
    setActiveTab(index);
    menuRef.current?.scrollSelectedToBlock(index);
  };

  const onBlockIntersection = (index) => {
    setActiveTab(index);
  };
  return (
    <>
      <div className="sticky-top bg-light">
        <div className="containr">
          <Tabs activeTab={activeTab} onTabClick={onTabClick}>
            {/* generating an array to loop through it  */}
            {[...Array(20).keys()].map((item) => (
              <Tab key={item}>Tab {item}</Tab>
            ))}
          </Tabs>
        </div>
      </div>
      <div className="row mx-auto justify-content-center">
        <div className="col-md-12">
          <Menu
            onBlockIntersection={onBlockIntersection}
            activeBlock={activeTab}
            action={menuRef}
          >
            {[...Array(20).keys()].map((item) => (
              <MenuBlock key={item}>
                <div className="display-4">Block {item}</div>{" "}
                <div className="row">
                  {[...Array(8).keys()].map((card) => (

API

Menu

Name	Default	Type	Description
activeBlock*	-	integer	the selected block value which must be passed to the commponent, and it's the same as activeTab state (I'm using it just to know what is the initial state of the block so I can scroll to it on the first mount)
onBlockIntersection*	-	function	function(event, value) => void callback function fires on block intersection. When you scroll to a certain block this function fires. It has two props, the first one is the event object of window.onscroll function the second one is the intersected block index
action*	-	ref	react ref fires when the component mounts. you must use it in order to use the scrollSelectedToBlock function inside onTabClick function and pass the index to it in order to scroll to the block when you click the tabs: ref.current.scrollSelectedToBlock(index)
containerClassName	-	string	sets the container className of the blocks
indicatorClassName	-	string	sets the indicator className
indicatorTopPostion	80	integer	sets the top position of the indicator. Note : the indicator is the point where the page's scroll will stop, where a certain block overlaps with the indicator, the onBlockIntersection will trigger, so by changing the top position of it, you can control where the page will land and where the onBlockIntersection will trigger.
showIndicator	false	indicator	if you want to show the indicator so you can know where it's exactly located in the page so you can customize its position
scrollBahavior	"instant"	string	the bahavior of window.scrollTo() function that I use it to scroll to the selected block. default instant but you can change it to "auto" or "smooth"

MenuBlock

Name	Default	Type	Description
className	-	string	sets the className of MenuBlocks container div
{...props}	-	object	I'm usign props spread operator so basically you can use anything
