Manually Positioned

For some special case, you may want to manually position the dropdown. For example, right click to activate dropdown in some area.

<div style="width: 200px; height: 200px; background-color: rgba(0, 128, 0, .5);" @contextmenu="handleContextMenu">
  Right Click
</div>
<n-dropdown
  placement="bottom-start"
  trigger="manual"
  manually-positioned
  @select="handleSelect"
  @blur="handleBlur"
  :x="x"
  :y="y"
  v-model="showDropdown"
