[Gelöst] Displaying a custom taxonomy as dropdown list in a widget

I am trying to: create a dropdown widget for a custom hierarchical taxonomy called locations.

I visited this URL:
https://toolset.com/forums/topic/show-taxonomy-in-a-widget-2/
And it seems like a good idea. But it looks like this goes in the php template rather than in the functions.php file.

How do I register a custom taxonomy as a custom widget in WP?
Or am I going about this the wrong way?

In my attached screengrab you can see my custom taxonomy - dislpayed as a custom menu in a sidebar widget. Ideally I'd like all of this to appear in a dropdown list as it's taking up a lot of space.

It seems like this question comes up a lot and I've been searching the forum for over an hour and nothing I've tried has worked.

Thanks for your support!

Hello. Thank you for contacting the Toolset support.

Well - I need bit more information. You just wanted to display hierarchical taxonomy in dropdonw only. Do you need any action with dodrpdown?

There is a workaround but it is workaround that needs some fixes.
=> Create a custom search view
-- https://toolset.com/documentation/user-guides/front-page-filters/
=> Add taxonomy filter by clicking on "New Filter" button from section "Filter Editor" and Submit button
=> from section "Custom Search Settings" select option:
-- Let me choose individual settings manually
-- Always show all values for inputs
=> Head to Appearance > Widgets and include the "WP Views Filter" Widget to your preferred Widget Ready Area and configure it
=> Hide 'submit' button using some CSS or JS

OR
