How to keep sidebar visible when navigating between interfaces inside a PanelLayout?

Hi everyone,

I have an interface built using a PanelLayout.

• The left panel contains a sidebar with several navigation links.

• The right panel displays the selected content (different interfaces).

The issue I'm facing is that when I open a page from the sidebar, everything works fine — the new content loads on the right and the sidebar stays visible.
However, inside that loaded interface, I have more links (for example, to open details or other sections). When I click one of those links, the page reloads completely and the sidebar disappears.

What I want is for those inner links to update the right panel within the same page, keeping the sidebar fixed and visible at all times.

Is there a way to handle this navigation within the same interface (e.g. using local variables and conditional visibility), or any best practice for managing nested navigation inside a PanelLayout?

Thanks in advance!
