Dropdown dynamic offset v4

[romanlex]

Hello. I'm trying change dynamically position of the dropdown menu. My code is not work ((( How I can calculate and change position of dropdown dynamically before dropdown is showing?
Example, I trying change data attr of element data-offset on show.bs.dropdown or shown.bs.dropdown

this.$parentUl.siblings('.dropdown-toggle').attr('data-offset', '-100').data('offset', -100);
this.$parentUl.siblings('.dropdown-toggle').dropdown('update');

Popper.js already handle that for you 👍

EDIT:

Hmm sorry I misunderstood your question @romanlex, I'm not sure if Popper.js handle to change the offset dynamicly, maybe a simple you can try :

this.$parentUl.siblings('.dropdown-toggle').dropdown('dispose').dropdown({
  offset: '-100'
})

I found what I can send fn function in offset to Popper

But in source code (dropdown.js) I see only static offset for initialize plugin in modifiers

that's true currently we only accept : number | string but we are open for a PR 😄
