Search of elements in the Jquery form styler?

There is jquery plugin jquery form styler
Modifies form elements

Trying to find the elements using js, but can not find
let liSelect = document.querySelectorAll('.jq-selectbox__dropdown');

It turns out the layout is not the selector. It is created when loading the plugin.
Bakc to solve?

to write code after the connection and activation of the plugin
Yes, after writing. Just turns out if in a browser, open the console, then it has these elements. If you open the source code of the page, then no. - Benjamin.Reichert commented on April 7th 20 at 15:50
@helga_Auer, show at least pieces of code, maybe it's something to give - ardith_Parisian commented on April 7th 20 at 15:53
This layout


Connect this script

In the end in the console


Here I need to get to the select, if that select has happened. - Benjamin.Reichert commented on April 7th 20 at 15:56
Accordingly, I need the items lie in jq-selectbox__dropdown
To can get, to rest with him there. - Benjamin.Reichert commented on April 7th 20 at 15:59
first of all why?
secondly the plugin has an API
Why without a need to change the CSS via JS - cydney37 commented on April 7th 20 at 16:02

Elements appear likely at a time when the select is OPENED.
And yet there is in colbecki. These are backlinks which will be triggered when it's their call.
Example : onSelectOpened

$('input, select').styler({
 fileBrowse: 'Select',
 singleSelectzIndex: '999',
 onSelectOpened: function() {
 // open select is added the red stroke
 $(this).css('outline', '3px solid red');
