Autoforge Viewer canvas won't resize after open sibling container

I have 2 element rendering in a same parent element one of them is a parameter container that can open and close and other is forge viewer. At 876px width this parent element gets flex-direction:column ; . When i open parameters container and go below 876px and close the parameter container forge viewer canvas size wont resize and white blank space appears.

I look up other similar questions but that didn't work for me.

I see that you're already calling viewer.resize which should update the rendering context accordingly. If that's not working, I'd suggest to try the following:

• when you end up in the "broken" state where the viewer is not rendering the entire object, try opening the browser console, and type NOP_VIEWER.resize(); if that resolves the issue, it's possible that your code isn't calling the viewer.resize method at the right time

• are you perhaps using any animations when opening/closing the parameters UI? If so, try and disable them, or make sure that the viewer.resize is called after the animation is complete

• check the browser console to see if there are any errors or warnings that could be related to the incomplete rendering
