I am creating a presentation in LaTex using the beamer document class. I am using the Hannover theme. This produces a navigation bar on the left hand side of each slide.
I have a lot of sections and subsections. These are indicated on the navigation bar. The problem is that these overflow the navigation bar. Neither do I want to delete any section or subsection nor do I want to make the text in the navigation bar smaller.
But still, I want the navigation bar to show all the "relevant" sections and subsections (along with the previous and next ones). How do I achieve this?

Here's an MWE (a screenshot of how the navigation bar looks like when there are too many sections and subsections):
As you can see, the navigation bar is overflowing. I do not want this to happen. Instead I want the following to happen:
Whenever I am presenting a section, only that section (and it's subsections along with the name of the previous and next section only) must be displayed on the navigation bar - nothing else. If I move onto a next section, only this section (and it's subsections along with the name of the previous and next section only) must be displayed on the navigation bar - nothing else.
How can I make this happen?
