Missplaced dropdown and not closing when clicking outside multiselect on select2

Question

As you can see on this example below, when I center the elements of my page with a margin in auto, the dropdown is misaligned. Moreover, clicking outside the dropdown does not close it automatically, which should be the case (clicking on the sides and below the dropdown causes the problem).

There is my code :

 $(document).ready(function () { $('.multiple-select').select2({ closeOnSelect: false, }) })

 html, body { margin: auto; background: #fafcff; font-family: 'Open Sans', sans-serif; font-size: 18px; color: #8a91b4; width: 60%; } /* Select2 CSS */ .select2-container { box-sizing: border-box; display: inline-block;

Add position: relative; to the element above the form ( body in your example)
