Parent child relationship for a Dropdown Box in UI Table

In this blog I will share the header item relationship  for Dropdown Box in a UI Table . Take an example like there are two Dropdown Boxes i.e One Header and other is Item Dropdown Box . When an header item is selected from Header part the corresponding items will be added in the Item Dropdown box.

It is easy in Normal case but a bit tricky if the Dropdown Boxes are in a UI Table , i.e When a header item is selected in any row of the UI Table then the corresponding Child Items will be added in the item Dropdown box of the same row. No other Dropdown boxes would be affected only corresponding rows will be affected.

I will explain  the above scenario with a simple example .

Scenario :    When a header item is selected in any row of the UI Table then the corresponding Child Items will be added in the item Dropdown box  of the same row only.

Below is an Array of Header-Items in a tabular format for simple understanding.
