I am trying to create a list as shown in the attached image. Here i have'nt created the seperate list for 5804 (which is like parent list). To avoid sparsity & size constrain, i am trying to create parent & child list in the same list. I know how to create in the tool for less items. Can someone tell me how to use Import data to create such list with bulk data.
I believe the issue is that you are still in blueprint view of the module when trying to import the data. If you change the view back to Grid view and then import the .csv you will be able to follow the next steps.
