Dash Prevent Refreshind/Resetting All Items When Switching Page

does anyone have an idea how to prevent dash to refresh the page when switching between pages. For example, being at page1 having created a plot with a lot of items (dropdown menu, radiobuttons, etc.) and then leaving page1, going to page2, selecting other stuff, and if I then return to page1, the plot should be still there and the items should be still in the same state and not initialized again.

Is there someone that can help me? It is very urgent and I cannot find out how to do this?:frowning:
