make reactive SelectInput value to render the coupled chart when clicked

what i am trying to do when the category RAJ is selected or clicked it must render the first part of plott2 chart that has TITLE RAJ in the example given below and if other-state is clicked then it must render the else part of plott2 and then it must render the subset values of RAJ in below given select input value and then it will display the subset chart of raj and so on same for the other state whether we click on parent chart for childchart or just select the value from selectinput box to plot the chart,i know it kinda confusing but i am not looking for anyone to do this entire long process

what i am looking for just an idea to get it done.
