Hi Tasubili,

On dropdowns, when selecting them, on the right properties pane, you will see below the OnChange event. There you can add a screen action as a handler:

This event will be triggered when a value in the dropdown is selected. There you can define the logic you want to be ran once a dropdown value is changed.

In your case, you want, to pick up the user selected, add it to the selected user list, remove it from the dropdown list, and set the selected value of dropdown list to null, I believe.

You can do all this, by using simple assigns and using the List actions from System:

For instance, you can use the ListAppend to add an element to a list and ListRemove to remove an element from a list.

Kind Regards,
João

Hi, Ravi

The requirements you are asking for the Dropdown is not possible because if you remove a selected value in Dropdown showing list, it will not show the value which is selected.

But it will possible with the "search dropdown".

i have given the oml please go through it.

I hope this might match your requirements
