i confirm that Item inspector can do it but you need to do a little configuration to get it.
First you need to configure a Popup Element to Part Of Speech to get the part of speech displayed in the popup data.
Next you need to use a filter to display only the items that belongs to a particular part of speech. You may choose between two filters for this purpose.
You may use the Advanced search filter:
- Select the All Wanikani Items table.
- Check the Used In selection for Part Of Speech
- Type in the desired part of speech in the Search Term field. A hover tip will tell you which part of speech are available.
- This will return a list of all items that have the selected part of speech.
- Moving the mouse over the item will reveal the information in a popup.
You may also use the Part Of Speench filter to achieve the same effect.
- In the Optional Filters settings select Part Of Speech
- Refresh your browser to enact this setting.
- This will cause the Part Of Speech filter to show in your browser settings.
- Select the All Wanikani items table.
- Use this filter to select a part of speech.
- This will return a list of all items that have the selected part of speech.
- Moving the mouse over the item will reveal the information in a popup.
