Forms - textarea - resize popup via preview options
I'm trying to resize the preview popup on my textarea via preview_options but it doesn't work. Please check the code below.
(inside my model)
$fields['page_content'] = array(
'label' => 'Page Content',
'comment' => 'Set the content of your page',
'type' => 'textarea',
'class' => 'markitup',
'preview' => '_mypage',
'preview_options' => 'width=200,height=200'
The size of the popup doesn't change (inspecting via chrome developer tools, the dimensions seem fixed at 864x508). Please let me know if i missed something or how to resolve this.
