Add a Canvas Form Control in Drupal Custom Module Im currently developing a module and I have this code in html:

&lt;canvas id="cnv" name="cnv" width="500" height="100"&gt;&lt;/canvas&gt;


I want it to add in my page using form controls but when I scan through Form API Reference, there's no canvas form control available. How to make it possible in Drupal? Any idea?
The form api does not support every tag in HTML. For special cases use a form key of #markup to embed raw HTML. Scan the form APIs for that keyword for examples.
