Print raw html strings on EJS
You should use html code everywhere, and use the EJS tags only where you need dynamic data. Example:
<a href='<%= user.id %>'><%= user.name %</a>
To specifically answer your question you can use <%- "<tags_here>" %>
to output unescaped HTML data.
for raw output html in ejs you can use this code
<%- "<a href='#'>Test</a>" %>
