I don't understand what you need.
Something has to get fixed somewhere.
If the bottom sheet goes to zero when the selection is cleared, what do you want the main sheet to do?
Main sheet is going to offer selection and once any of the stacked bar is selected, its relevant data will be shown in the bottom sheet and this bottom sheet is causing resizing of the main sheet. Show and Hide of the bottom sheet is working fine in the current dashboard.
In the current implementation, bottom sheet is not fixed in all three categories selection. When you click blue bar it will popup to a different height than clicking on a orange bar.
Now I want the bottom sheet to behave like a defined fixed height sheet such that when it pops up it pops up to a defined fixed height no matter which category/bar a user select and in case of no selection it should hide and main sheets expands till the bottom area.
size the three sheets on dashboard ? I have probably not picked up rightly...could you kindly elaborate please?
Your office furniture and technology sheets are already sized the same. You just need to mess with the sizing of the furniture sheet so that it comes out the same height on the dashboard. Make the changes in the sheet itself. Widen the rows. A little bit at a time. See how it renders on the dashboard.
You want three different object to push the main data sheet an identical amount, so you have to make those three objects the same height. But you also don't want to set a fixed height on those three sheets because they'll occupy that space even when they're not displayed.
It would be a lot easier to leave the main sheet shortened to the height you want the three lower sheets to push. Then you could make a container below the data sheet that has a fixed height, and then the three detail sheets could pop open in it with a "Fit Height" setting to fill that height no matter how much data is in those sheets.
Yes I agree with your last point...but thats the problem I dont want to do that and let it be dynamic. I just somehow want to set the maximum height limit for the bottom sheet so when it pops up is should not go beyond the set maximum height.
