Scene description:
1. Popup button turns on/off the Categories in the ScrollView with a Table.
2. Each Category contains a ScrollView with a Grid.
3. Each Category is a prefab that's dynamically added to the Table.
Problems:
1. When the Categories are added, the items are not placed correctly. Have to click on the Category header to make it align properly. In the code that generates the Category, Table.Reposition() was called.
2. items are not being clipped by the outer Category scrollView. This is intermittent,sometimes working other times not.
3. Item buttons disappear intermittently upon enabling,disabling of the Categories.
4. Edit: Now in the video: when there are multiple items in the row and the row is dragged to the left, the entire Category row jumps to the right. This was mentioned in another posting that has a prefab of the scene.
Here is a video clip showing the above problems.
