Hi @DICT-OKTOX
You can use the for each UI element activity to check a item in the list of items in the drop-down.
Follow the below steps,
→ Use for each UI element activity and indicate on one of the item then it will automatically extract all the items in the drop-down list.
→ Come back to studio click on configure Filter option in the for each UI element activity and pass the variable contains which items has to check. output of for each UI element activity is CurrentElement.
→ Inside for each UI element activity insert the Check/uncheck activity and open the properties, find the input element option and pass the CurrentElement to it. (If you want to check the item then use check/uncheck else use click activity)
It works for you.
Hope it helps!!
