I have installed jQuery UI Filter and jQuery plugins to get text with accordion effect. It works perfectly when the content is inserted in a node, with a special tags language. However, when I try to get the text rendered in a block with hook_block_view_VIEW_NAME_alter, as I am just the $data["content"]["#markup"] property, it is not working and it is displaying the special tags without rendering them: [accordion], etc.
Must I get the effect by using clean jQuery instead of the modules? Is there a way of saying that I want to apply the "Full HTML" properties to the content-markup text of the block?
