You can attach to a layout various items from tree to web pages. The items, you can add, are:
You can refer to an item as a collection, where [0] is a zero-based index of a certain item. All the items have their own indexes. Indexing starts with 0.
However, the other method is extensive used: through layout items' ids. All the items have ids that go in an alphabetical succession and start with “a”. And in this case you refer to items as cells.
var item = dhxLayout.cells("a"); // or var item = dhxLayout.items[0];
