How to make use of it:

1. Install and import the Box Selection.

# NPM
$ npm i box-selection --save

module.exports = require('./lib/box-selection')

2. Add items to be selectable to a container component as follows:

<div class="wrapper" id="container">
  <div class="item"> </div>
  <div class="item"> </div>
  <div class="item"> </div>
  <div class="item"> </div>
  <div class="item"> </div>
</div>

3. Create an instance of the Box Selection and executed.

const instance = new BoxSelection({
      // default: the whole document
      container: document.getElementById('container'),
      // default: .item
      itemSelector: '.item'
})

4. Get the selected items using the onSelectionChange callback.

const instance = new BoxSelection({
      onSelectionChange: (selectedItems) => {
        console.log(selectedItems)
      }
})

5. Customize the styles of the selection box.

const instance = new BoxSelection({
      selectionClass: '.selection'
})

.selection {
  background-color: rgba(255, 255, 255, 0.5);
}

6. Customize the styles of the items when selected.

const instance = new BoxSelection({
      selectedClass: '.selected'
})

.selected {
  background-color: #222;
}

7. Determine the selection mode: ‘strict’ or ‘loose’.

const instance = new BoxSelection({
      mode: 'loose'
})
