There is a plugin Jquery q does this. It is very easy to use, link: https://jqueryui.com/selectable/

$( function() {
    $( "#selectable" ).selectable();
  } );

#feedback { font-size: 1.4em; }
  #selectable .ui-selecting { background: #FECA40; }
  #selectable .ui-selected { background: #F39814; color: white; }
  #selectable { list-style-type: none; margin: 0; padding: 0; width: 450px; }
  #selectable li { margin: 3px; padding: 1px; float: left; width: 100px; height: 80px; font-size: 4em; text-align: center; }
