Current Result : iX angular app (forked) - StackBlitz
Expected Result :
Hi @udayakumar.sundaramurthy, correct, the toast has a fixed width to encourage short and concise message texts. You could integrate a link to provide more information about a message and/or consider using a modal to communicate longer explanations.
Nevertheless, we have a design update in backlog that also includes the consideration for a wider width, but the width will remain fixed.
