Tags/Layers

Hi, Im working on a windows and having trouble tagging components. Once I have selected floor or roof for example I am unable to click on the floor tag in the default tray. In my options menu/windows there is no tag/layer drop down either. Can anyone point me in the right direction please?! Thanks

Are you talking about selecting the tag to assign it in Entity Info?

What Options menu?

Can you post a screen shot of what you see in the tray?

This is what I see.
