How to prevent reloading _Layout.cshtml in asp.net cor mvc

Hi

 

I have a side bar as shown below

 

This is the orginal state.

 

Pic-1

 

Pic-2

after expanding

 

 

The problem is, whenever i click on the links in the side bar (its a list) the whole page gets reloaded. That means the list goes to the orginal state as in pic-1.  I know this is because of @renderbody() method. But I cannot use @RenderPartial beacuase i have muliple view pages to pass on.

 

Is there any way to load only the @RenderBody() area without changing list state.
