Position in Angular Toast component

19 Oct 202418 minutes to read
Toast position can be updated based on predefined positions or user customizable positions. Predefined position combinations are updated in X and Y position properties.
Predefined

X Positions
Left
Center
Right
Y Positions
Top
Bottom
In the case of multiple Toast display, new Toast position will not update on dynamic change of property values, until the old Toast messages removed.
Toast occupies full width when we set width as ‘100%’, so X positions won’t affect changes when ‘100%’ width.
Custom

Custom X and Y Position can be given as pixels/numbers/percentage. The number value is considered as pixels. based value top and left value updated in the toast.
