Dreamweaver no longer populates command menu in latest version of iOS. If I right click on a cell and open the menu it no longer has any options when you click on table, paragraph, list, font, etc...

Given that it happened when you installed the new OS, I would recommend reinstalling the app. You may have to use the cleaner tool that is linked in this thread. Before you do, I would recommend you backup your site definitions since you are still able to open DW. This way you can start right back up by importing the definitions when you reinstall: https://helpx.adobe.com/dreamweaver/using/import-export-dreamweaver-site-settings.html . Also ensure that you are updating DW to the latest version as well in the process as there were some known issues when Tahoe was first released that have been fixed in later updates.

Have you restarted your computer? 

Failing that, you might need to perform a clean reinstallation of apps after running the Adobe Cleaner Tool below. See links for more details.
