In Chapters 2 and 3, we saw how to make use of different form fields, containers, and layouts to create a view of our choice. The out-of-the-box layouts provided by Sencha Touch have a pre-defined way to position the components and calculate their sizes. Often, there may be situations in the application where the view cannot be created, directly using the available containers, components, and layouts. For example, if we wanted to create a photo album where the view shows the photos in a matrix based on the dimension of the device.
