ABAP: Get super container of DROP_DOWN_BY_KEY

Question

Hello,
I have some dynamic behavior on the screen that I am working on:
Transparent containers generated dynamically. Each of newly generated containers has a DROP_DOWN_BY_KEY.
When a user selects an item from that DROP_DOWN_BY_KEY I need to get reference to a container where this DROP_DOWN_BY_KEY is in.
Parameter WDEVENT of type CL_WD_CUSTOM_EVENT can access the following methods:
CONSTRUCTOR
GET_NAME
GET_BYTE
GET_CHAR
GET_FLOAT
GET_INT
GET_OBJECT
GET_STRING
GET_CONTEXT_ELEMENT
GET_DATA
Which one should be used to get reference to the container?
Is there a different way?
Thank you.

Hello Armin,
It is a looooong way to wite it all up.
Shortly, there is a DROP_DOWN_BY_KEY that generates elements (input fields, DROP_DOWN_BY_KEYs, etc.). Each drop down should be able to change some elements that correspond to this drop down.
In order to know which elements shold be modified/touched I need to have a reference from each drop down to elements that correspond to each of the drop downs.
For example:
DROP_DOWN_ONE: element one, element two, element three
DROP_DOWN_TWO: element five, element six, element seven
DROP_DOWN_THREE: element eight, element nine element ten
DROP_DOWN_FOUR: element eleven, element twelve, ...
Each drop down with corresponding elements resides in individual transparent container.
so when a user selects some option from DROP_DOWN_THREE it should access only the following elements:
element eight, element nine element ten
I was thinking to get those elements from action since they reside in individual containers. Something like:
actionNAME->getParentUIElement ...
Thank you.
