Just published the Druid 0.9.1 (without release, just a tagged version) The next release is in process 
Update DataList and add the example with DataList + Custom component
Add two events to DataList: data_list.on_element_add and data_list.on_element_remove to have more ability to custom the behaviour
New functions:
data_list:get_data()data_list:get_created_nodes()data_list:get_created_components()
It’s also allow you to manage your nodes more 
Even the behaviour of ‘one selected’ can be implemented in several ways, choose the way you like more. DataList is more complicated than general scroll + grid components and it’s required more management. But if you wanna use this component, let’s learn the examples and source code.
Thanks for your feedback!
