+^^^position
+Denotes the target element of the popover. Used with [Popper.js](https://popper.js.org/)-style placement syntax, see [`Popper.placements`](https://popper.js.org/popper-documentation.html#Popper.placements).
+^^^
+
+^^^trigger
+The event that triggers the toggle of the popover. Can take valid values for `v-outside` directive's `trigger` parameter, and can use <code>&#0096;${open}-${close}&#0096;</code> syntax to specify different trigger event for showing/hiding the popover. When specified as `custom`, `v-outside` will not be leveraged to automatically toggle the popover.
+
+eg. `click` denotes showing the popover after clicking the `target` and hiding it after clicking outside. `hover-mousedown` denotes showing the popover after hovering the `target`, and hiding it after clicking outside.
