List in Dropdown

Question

Hello!
I have a list of "things" that i want to show in a dropdown box, in a table. The list is not static (it's not a enumeration) is created in a backend system.
I want for example select Element1 on the dropdow at the line 1 of the table, and the element should not be avaiable in the other lines of the table.
What is the best solution to do this?
Where to bind the dropdown, what kind of context i need?
Greetings!

Hi João,
Create the below nodes.
1. A singleton node for table
2. A Non-Singleton node for dropdown which should be a child node of table node. Create a context under this node which should be bound to the dropdown UI element in the table
Now, for the functionality that the element selected in one row of the table should not be displayed in the dropdown of any other row, you can use the below logic
Create an event for dropdown and write the below code for it.
String selectedDropdownElement = wdContext.currentTableElement().currentDropdownElemnt().getDropdwnContext();
for(int i = 0; i < wdContext.nodeTable().size; i++)
        //now populate the dropdown in set of the table rows if the selectedDropdownElement if not equal to that element
        //Suppose you have the values for the dropdown in a node
        //Dont run the outter for loop for the current element
        //Copy data from backend node to table dropdown node
        for(int k = 0; k < wdContext.nodeDropdownBackend.size(), k++)
               if( ! wdContext.nodeDropdownBackend().getDropdownBackendEleementAt(k).getDataAttribute().equals( selectedDropdownElement))
                     //Create mode for the dropdown node in the table 
Hope this helps you.
