Help displaying text

Apologies in advance ...this may be a really dumb question but here goes.

@formatted_question[:a] contains text with HTML markup. I want to display it in a field so I can control its vertical and horizontal size on the page. When it is displayed on the page now, rather than interpreting the HTML, it is output into the text field as a string with all HTML tags showing. What am I doing wrong??

<div id = "A">     <%= text_area_tag id="cka",(@formatted_question[:anno_a]) %> </div>

Any help would be greatly appreciated

Misusing a form element :slight_smile:

<div id = "A">     <%= text_area_tag id="cka",(@formatted_question[:anno_a]) %> </div>

That's the way a text area works; if you want to control display size, use CSS to size the appropriate block-level container (e.g. div, p).

Also, you need to indicate that the contents should not be escaped, but delivered as-is to the page:

<div id="cka">   <%=raw @formatted_question[:anno_a] %> </div>

Note the ERB tag begins "<%=raw" That 'raw' is raw (ActionView::Helpers::OutputSafetyHelper) - APIdock and will send the actual contents, i.e., the HTML, to the page.
