Positioning

There are three ways of positioning. The default is as a sibling of the parent element, the other posibilities are as a child of the parent element, or on body.

  • The sibling/parent positioning can be problematic when you have an overflow:hidden as a parent to the nearest element with position:absolute|relative|fixed and the dropdown is overflowing.
  • the body positioning can be problematic when the parent is moving relative to body or when you depend on inheritance of styles.
Transition

You can provide a vue transition like this:

Vue.transition("fade",{
  // your transition
})
// or in the instance:
transitions: {
  fade: {
    // your transition
  }
}
// usage:
template: "<dropdown transition='fade'></dropdown>"

You can access several properties in your enter hook:

enter: function(el,cb) {
  // style properties as numbers
  this.top
  this.left
}
