How to display string that contains HTML in twig template?

To display a string that contains HTML in a Twig template, you can use the raw filter. This filter tells Twig to not escape the string, so the HTML code will be rendered as HTML rather than being displayed as plain text.

Here is an example of how you can use the raw filter:

{% set myHtmlString = '<h1>Hello World</h1>' %}
{{ myHtmlString|raw }}

This will display the string as an h1 element, with the text "Hello World" being displayed in the browser.

It is important to be careful when using the raw filter, as it can potentially expose your application to security vulnerabilities if the string contains malicious code.
