What is selecto?

Selecto is a JavaScript library that allows users to select multiple elements by dragging a selection box over them. It is highly customizable and can be used in various scenarios such as image galleries, file managers, and more.

What are selecto's main functionalities?

Basic Selection

This feature allows users to select elements by clicking and dragging a selection box over them. The selected elements are highlighted by adding a 'selected' class.

const selecto = new Selecto({
  container: document.querySelector('.container'),
  selectableTargets: ['.selectable'],
  selectByClick: true,
  selectFromInside: true,
  hitRate: 100,
});

selecto.on('select', (e) => {
  e.added.forEach(el => el.classList.add('selected'));
  e.removed.forEach(el => el.classList.remove('selected'));
});

Custom Styling

This feature allows users to customize the appearance of the selection box by specifying styles such as border and background color.

const selecto = new Selecto({
  container: document.querySelector('.container'),
  selectableTargets: ['.selectable'],
  selectByClick: true,
  selectFromInside: true,
  hitRate: 100,
  selectionStyle: {
    border: '2px dashed #000',
    backgroundColor: 'rgba(0, 0, 0, 0.1)',
  },
});

Multiple Selection

This feature allows users to select multiple elements by holding down a modifier key (e.g., Shift) while clicking or dragging.

const selecto = new Selecto({
  container: document.querySelector('.container'),
  selectableTargets: ['.selectable'],
  selectByClick: true,
  selectFromInside: true,
  hitRate: 100,
  toggleContinueSelect: ['shift'],
});

selecto.on('select', (e) => {
  e.added.forEach(el => el.classList.add('selected'));
  e.removed.forEach(el => el.classList.remove('selected'));
});

🚀 How to use

Option Behaviors

• If you want to prevent select from inside and no click
  • selectFromInside: false
  • selectByClick: false (default)
• If you want to include it regardless of hitTest when selecting from the inside
  • selectFromInside: true (default)
  • selectByClick: true
• If you want to finish right away (selectStart and selectEnd occur at the same time) without dragging when selecting from inside
  • selectFromInside: false
  • selectByClick: true
  • preventDragFromInside: true (default)
  • clickBySelectEnd: false (default)
• If you want to selectEnd(click) after stopping drag and mouse(touch)
  • selectFromInside: false
  • selectByClick: true
  • clickBySelectEnd: true

import Selecto from "selecto";

const selecto = new Selecto({
    // The container to add a selection element
    container: document.body,
    // Selecto's root container (No transformed container. (default: null)
    rootContainer: null,
    // The area to drag selection element (default: container)
    dragContainer: Element,
    // Targets to select. You can register a queryselector or an Element.
    selectableTargets: [".target", document.querySelector(".target2")],
    // Whether to select by click (default: true)
    selectByClick: true,
    // Whether to select from the target inside (default: true)
    selectFromInside: true,
    // After the select, whether to select the next target with the selected target (deselected if the target is selected again).
    continueSelect: false,
    // Determines which key to continue selecting the next target via keydown and keyup.
    toggleContinueSelect: "shift",
    // The container for keydown and keyup events
    keyContainer: window,
    // The rate at which the target overlaps the drag area to be selected. (default: 100)
    hitRate: 100,
});

selecto.on("select", e => {
    e.added.forEach(el => {
        el.classList.add("selected");
    });
    e.removed.forEach(el => {
        el.classList.remove("selected");
    });
});

Do you want to select accurately?

Since selecto basically checks using getBoundingClientRect, it is not accurate if the object is rotated or distorted.

If you want to check accurately, use getElementRect option with the following code

• See Example

import Selecto from "selecto";
import { getElementInfo } from "moveable"; // (13kb function) if you use react, use react-moveable

const selecto = new Selecto({
    ...,
    // (target: HTMLElement | SVGElement ) => { pos1: number[], pos2: number[], pos3: number[], pos4: number[] }
    // pos1: left top
    // pos2: right top
    // pos3: left bottom
    // pos4: right bottom
    getElementRect: getElementInfo,
});
