Reloading a page from selecting a taxonomy term from a views filter
No need for contrib modules: it's all in Views.

So firstly you'll need to add a Filter criteria in your View.


Add
Select the term field (Topic in my case)
Configure extra settings: Dropdown
Configure filter criterion: Expose this filter to vistors


Secondly you'll need to enable AJAX submits.


Advanced > Other > Use AJAX > Yes




There are a couple of contrib modules that may be useful however.


Chosen for very long select lists
Better exposed filters if Select lists aren't good in your case
