Hi Pavan,
I think the best way to do this by using conditional visibility. You can have the onClick on your map to set a boolean, which you use ase a identifier for ‘visible’ or ‘hidden’.
Something like : Onclick → call Microflow -→ in the microflow set attrBoolean = not(attrBoolean). Then use the boolean in the container (visibility property) that holds you object list.
This boolean is either true or false and it repondse on the value you give when clicking on your map.
Hope this wil get you going,
Jan
