title: How to select all options in select2 JavaScript multiselect
body: <p>The other day, I was trying to figure out how to select all items in select2 v3.5.1 JavaScript multiselect control. I tried a few things, but I was having a difficult time figuring out how to do it. I just wanted to select every option in the box, but apparently select2 does not have a built-in option to select all of the items for you.</p>
