View Canvas renders and allows interaction with UI elements in the View. You can open View Canvas either from the Context page or from the Action logic editor belonging to a UI Context.
Various levels of interactions are possible in the View Canvas. When you hover around the canvas, system tries to identify the nature of element encompassing the mouse pointer and provides a tooltip on the highlighted rectangle.
In some cases, there could be multiple encompassing elements at a given mouse pointer location, with pretty close boundaries. When this happens, system tries to guess the most relevant of the group of matching elements and tag information about it.
However, if all the elements are equally relevant or a preferential selection is not possible, accelQ tags the entire rectangular areas as “Ambiguous”. When the user clicks on such a rectangular area, a modal is presented and the user is asked to choose one of the overlapping elements to analyze.
When you have a rich web application with a deep hierarchy of elements in the DOM, you may expect to see such instances.
