HELP create a feature like this (a block with hierarchy: selection by categories)

Hello at any time of the day!

I kindly ask for help in creating a feature. I will explain it more clearly, as I don't know how to write it briefly. I've been stuck on this for about 4 days without results.

In short, I need to create a block on the front page (in Drupal 7) where visitors can select a country, then a city, click submit, and be redirected to a specific page. For example, to a view page.

I have a simple view page (which also has pages) that displays materials based on a specific country and city. Each article has a taxonomy term nested within it: country, and then by hierarchy, city.

On my front page, I have panels and blocks. Besides this block for selecting the country and city, nothing else should be displayed. I have already tried Views + better exposed filter, hierarchical_select, simple_hierarchical_select, and their combinations. Nothing works. They are not suitable because they display information on the same page; they just filter.

I need this block for selecting the country and city to essentially exist only on the main page, while the materials are on other pages.

It might need to work in conjunction with Search.

Please let me know if anyone can provide a brief overview. Perhaps someone knows of a guide or available modules.

Yes, I am not a programmer, so this is difficult for me. Although I understand that it shouldn't be too hard if I were to write the code myself. Alright.

Thank you very much in advance for any help!
