Render Markdown
Let's imagine that you want to create a sidebar box in your theme, and the user should be able to add text and use Markdown to format it, e.g. add a link. You can realize this with the {{ markdown() }}
helper function in two steps:
In the first step you define a textarea for the sidebar widget in the YAML-file of your theme like this:
sidebar:
type: textarea
label: Add some text for the sidebar with markdown
placeholder: Add markdown here
Then you can render the Markdown content in your theme like this:
<div class="sidebar-box">
{{ markdown(settings.myplugin.sidebar) }}
</div>
