     * @param {Object} options
     * @param {String} [options.placement=bottom]
     *      Placement of the popper accepted values: `top(-start, -end), right(-start, -end), bottom(-start, -right),
     *      left(-start, -end)`
     *
     * @param {HTMLElement|String} [options.arrowElement='[x-arrow]']
     *      The DOM Node used as arrow for the popper, or a CSS selector used to get the DOM node. It must be child of
     *      its parent Popper. Popper.js will apply to the given element the style required to align the arrow with its
     *      reference element.
     *      By default, it will look for a child node of the popper with the `x-arrow` attribute.
     *
     * @param {Boolean} [options.gpuAcceleration=true]
     *      When this property is set to true, the popper position will be applied using CSS3 translate3d, allowing the
     *      browser to use the GPU to accelerate the rendering.
     *      If set to false, the popper will be placed using `top` and `left` properties, not using the GPU.
     *
     * @param {Number} [options.offset=0]
     *      Amount of pixels the popper will be shifted (can be negative).
     *
     * @param {String|Element} [options.boundariesElement='viewport']
     *      The element which will define the boundaries of the popper position, the popper will never be placed outside
     *      of the defined boundaries (except if `keepTogether` is enabled)
     *
     * @param {Number} [options.boundariesPadding=5]
     *      Additional padding for the boundaries
     *
     * @param {Array} [options.preventOverflowOrder=['left', 'right', 'top', 'bottom']]
     *      Order used when Popper.js tries to avoid overflows from the boundaries, they will be checked in order,
     *      this means that the last ones will never overflow
     *
     * @param {String|Array} [options.flipBehavior='flip']
     *      The behavior used by the `flip` modifier to change the placement of the popper when the latter is trying to
     *      overlap its reference element. Defining `flip` as value, the placement will be flipped on
     *      its axis (`right - left`, `top - bottom`).
     *      You can even pass an array of placements (eg: `['right', 'left', 'top']` ) to manually specify
     *      how alter the placement when a flip is needed. (eg. in the above example, it would first flip from right to left,
     *      then, if even in its new placement, the popper is overlapping its reference element, it will be moved to top)
     *
     * @param {Array} [options.modifiers=[ 'shift', 'offset', 'preventOverflow', 'keepTogether', 'arrow', 'flip', 'applyStyle']]
     *      List of functions used to modify the data before they are applied to the popper, add your custom functions
     *      to this array to edit the offsets and placement.
     *      The function should reflect the @params and @returns of preventOverflow
     *
     * @param {Array} [options.modifiersIgnored=[]]
     *      Put here any built-in modifier name you want to exclude from the modifiers list
     *      The function should reflect the @params and @returns of preventOverflow
     *
     * @param {Boolean} [options.removeOnDestroy=false]
     *      Set to true if you want to automatically remove the popper when you call the `destroy` method.
