If you are using javascript, maybe you can do something like below.
However, this does not account the height of the container...
// whatever string
const myString = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum pellentesque sem ut consequat pulvinar. Curabitur vehicula quam sit amet risus aliquet, sed rhoncus tortor fermentum. Etiam ac fermentum nisi. Ut in lobortis eros. Etiam urna felis, interdum sit amet fringilla eu, bibendum et nunc.';
// you can set max string length
const maxStrLength = 100;
const truncatedString = myString.length > maxStrLength ? `${myString.substring(0, maxStrLength)}...` : myString;
console.log(truncatedString);
