You should just define the items in the model in needed order. Datagrid designed fully similar to standard h:panelGrid but iterating the model. So it's outputs the data in given order placing in defined number of columns.
Thank you for your answer.
Isn't there an other way then define all the items new... thats kind of expensive.
I found something in the h:selectManyCheckbox -> layout="pageDirection" that would be great with the dataGrid...
use just the base component - a4j:repeat. You will be able to create any markup based on iteration data.
well, that would be a possibility but i don't know how to use this with multiple columns ... do you have any suggestion for me?
