After many months of using the new Nav block, it fulfils almost all of our needs with only a few missing features.
The display of descriptions in the dropdowns is excellent and we have control over the styling, so when using either a manually constructed Nav menu with dropdowns or a multi-level menu loaded from the WordPress Appearance > Menus area, this works perfectly.
Unfortunately there is still one use case where we still need the filtering of the Menu block or an enhancement to the Nav block.
Currently we have a “My Account” menu that has an icon and a dropdown. To achieve this, we have used a Nav Dropdown with Custom Content enabled and a Menu block inside. This works very well except for displaying of the descriptions.
Currently as far as we can tell, there is no way to display descriptions under each item in a dropdown with a dynamically loaded menu. Both the Menu block and Nav block do not display descriptions at the top level, so even though they are laid out vertically, this doesn’t work.
If anyone has any clever suggestions or workarounds, please let us know.
