Prevent auto-resizing of panels when removing a side panel

[eliza-eliza]

Hi,
I have an application with two side panels and a main panel in the center. I want to disable the automatic resizing of panels when one of the side panels is removed.

Here’s the expected behavior:
1. Initially, there are two side panels and one main panel in the center.
2. When I remove the left side panel, the remaining side panel and the center panel currently resize automatically.
3. I want the remaining side panel to stay the same size while the center panel takes up all the available space.
4. The same behavior should apply when removing the right side panel.
5. At the same time, I want to keep the ability to resize the panels manually and allow the two side panels to be dragged into each other.

Is there any workaround or trick to achieve this?
