treejs

I have a working checkboxes code. This works totally fine when I coded it. But, in real project there is bootstrap css included as well. And with the presence of bootstrap css, the tickmark size got reduced inside the checkbox.

i use TreeJs to modelise a form and i want to move 2 parameter in the same slider i want to know if its possible : like moving x position of two differents vertices at the same time and not only one.

I already use datGui to move one vertice but i want to move more than one with the same slider.

I am using ztree in my component, there is a function named addHoverDom(treeId, treeNode), it's defined in the component, but it doesn't get called in the way that angular usually does. Below is the function:

Currently in the page we have a mesh loaded with TreeJS and displayed in a canvas:

How could we get the color of the point where we click on?

I have tried as it has been suggested here: Getting the color value of a pixel on click of a mesh with three.js , to create a canvas with a 2d context on top of the one using webgl context.

The problem is that when we convert the model to PNG, the image is white:

Our img 2d src:

If we click on it:

So then the console logs that the color is: 0 0 0 0

Also I will show the code where we generate the webgl canvas and the 2d canvas:
