My code from smarty template is as below. The disable="disabled" property is not working on text fields. Can you tell me why it's not working?
<input type="text" name="{$sheet_type}_{$subject_topic_data.subject_id}_{$topic_diff_level_data.topic_id}_{$key_diff_lvl}" id="{$sheet_type}_{$subject_topic_data.subject_id}_{$topic_diff_level_data.topic_id}_{$key_diff_lvl}" maxlength="3" class="mini" value="{$diff_level.added_no_questions}" disabled="disabled">
