There is a task to show two drawers in one component. One for the navigation menu, the second for additional information. And the main content of the page is a tree view with a lot of lines.
At the moment, I managed to insert two drawers onto the page, but the tree view starts to work incorrectly. If you scroll the data to the bottom, then the lines cease to be rendering. Example : https://codesandbox.io/s/left-or-right-position-devextreme-drawer-sr7zz
My question is, is this possible? If so, how to do it right?
Thank you for the example. TreeList cannot correctly calculate its height inside ScrollView because this widget has its own scrolling by default (see scrolling.mode). So, you don't need to use ScrollView in this particular case.
I've modified your example to demonstrate a possible implementation - https://codesandbox.io/s/two-drawers-with-treelist-xg0ww
I also changed openedStateMode to 'shrink' to make the vertical scrollbar visible if the left/right menu is expanded.
Let us know if this approach helps.
