Using a reference selector

I am trying to use a reference selector dropdown to load a data into a data grid. I have a checklist in a data grid and want it to 1.) only show when a project is selected and 2.) load in the correct checklist associated to the project selected. This seems to work with a reference set selector, but not with the dropdown. with this way I used a listen to widget. it seems as though a dataview cannot listen to another dataview though. Can anybody explain how I do this with a drop down?

Try using a wrapper entity (this can be non-persistent) that gets a association set based on your selection in the grid) then you can update the view with your dropdown via refresh and based on your selection in that view, create a microflow that saves everything to the actual object
