Hello @Samit Sahoo 

Here you have to append the selected item from dropdown to the Selected Item List of dropdown tag on the OnChange of dropdown.

Do share your oml if you find any difficulty doing that.

Thanks

I checked your application. 
Your description is not completely clear to me, but let me explain you what I understand. 

You have a project dropdown.

On Project selection, you get the task list.

On Task selection you want to select the same task in the dropdown tag? I believe this is your problem. 

If yes, the here is the suggestion.

In Dropdown tag, you will find a property "StartingSelection"

you can set a list variable in this property ( Data type: DropdownOption List, if you provide list which has other data type, you will get a mapping option to map the value appropriately )

If the DropdownOption list's options will be present in your source list (OptionList) it will automatically get selected. 

in your case. 

1. Create a new local variable and name it "DefaultTaskList" and set the data type: DropdownOption List
2. handle the OnChange event of Task Dropdown. 
3. append the select option to the the DefaultTaskList
4. Set the DefaultTaskList as a StartingSelection of Dropdown tag.

Hope this will help
