I am designing a control where the 1st column, 'Investment Categories,' corresponds with lots of purposes shown on the right. The users need to be able to add additional Purpose Columns as they work in the program.
I have a + icon next to the Investment Categories since the users need to be able to add additional Investment categories too.
I am stuck because I dont know how to show the user to add additional Inv Categories ( which adds rows) and additional Purposes (which adds Columns).
Should it be done via an icon, or text.... kinda lost. I appreciate you guys advice in advance.
