Connect an Element
Connectors are used to link elements and show flow direction. Elements can be connected to other elements depending on their type. The type of connector is indicated by its color.
Other ways to connect elements include the following:
Hover over the first element and click a blue arrow to link to an adjoining element.
Drag one element over another, hover over its blue arrow until it turns dark blue, and then drop to connect the elements. Connecting your elements this way auto-links them with the correct connector type.
Click an element from the toolbox, and then hover over an element on the canvas and click its blue arrow to drop and auto-link the new element.
Drag and drop a connector from the toolbox to the canvas, and then drag the ends of the connector to the elements you want to link.
