To change the order of the steps in a lab, you can move them in the list of steps on the right side of the webpage. To move a step, click and drag the icon for the step, then place it in the grey bar where you’d like the step to be. The grey bar will change colour when the icon is hovering over it. The step will now appear where you placed it and be numbered accordingly.
You also have the option of turning a step into a sub-step of an existing step. To do this, drag the selected step into another step in the list of steps on the right side of the webpage. The step will change colour when you’re hovering over it. The step will now appear after the main step and will be numbered as a sub-step.
