Positioning in Angular Toast component

21 Dec 2022 / 3 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.
