Floor Plan- Trouble selecting a whole room
I am new to Lucid Charts. I am using floor plan. I dragged a room onto the canvas. I want to expand it to the right, but I cannot seem to select by clicking on it with my mouse. If I click in the center of the room nothing is selected. If I click on a wall, it only selects the wall. I assume I am misunderstanding something. Can you help? Thanks!
