View design/Gui design

Question

Hi Gurus,
1.) The view which we design is because of drag and drop in WDA.
      But when a button or text feld gets created it is static . 
      How can we make the postion of that feld dynamic.
      For eg:
      I create an element say text box..it gets created at the top..
      what if i want to postion the same in the centre of the view.. How is this possible..?
2.) How can we create dynamic selection screen
Eg: We used to make screen-group = active etc in our report se38 programming.
Are there any methods for the same...?
Best Regards,
Navin Fernandes.

do u mean u want to create UI dynamically in ur view , u can use the concept of DYNAMIC PROGRAMMING in WD ABAP
To create a new node, the method add_new_child_node( ) can be used. This method hands back the reference to the metadata of the new node.
Dynamic Context AttributesAttributes for the dynamic nodes created can be created by calling the method add_attribute ( ) from the reference to the metadata of the node. This method has to be called once for each attribute.
However add_new_child_node ( ) method not only allows to create a context node, but also to create related attributes.
The interface of method wdDoModifyView provides a parameter VIEW, which is a reference to an object of type IF_WD_VIEW representing the instance of a view at runtime
check out my WIKI :
http://wiki.sdn.sap.com/wiki/display/stage/dynamiclayoutmanipulationinWD+ABAP
Procedure to create context nodes dynamically:
In order to create a new independent context node a reference to the metadata of the context root node has to be obtained first. This reference is obtained by calling the method
wd_context->get_node_info( ).
Next, the metadata of the new node has to be defined. To create a new node, the method add_new_child_node( ) from the reference to the context root node can be used. This method hands back the reference to the metadata of the new node. An important parameter of the method add_new_child_node( ) is static. Only if this parameter is set to abap_false can the related node can be deleted at runtime.
I am creating the drop down by index . I have used the reference using the attribute mr_view .
mr_view refers to the associated TYPE IF_WD_VIEW .
