+# Frequently Asked Questions
+
+
+<details><summary>Allowing dangerous HTML tags</summary>
+
+Sometimes it is useful to allow dangerous HTML tags to add interactivity to your notebook. One of the example is to use details/summary as a way to expand/collaps your todo-list.
+
+* How to enable:
+  * Go to **Preferences** → **Interface** → **Sanitization** → **Allow dangerous html tags**
+* Example note: Multiple todo-list
+  * Create new notes
+  * Paste the below code, and you'll see that you can expand/collaps the todo-list, and you can have multiple todo-list in your note.
+  
+```html
+<details><summary>What I want to do</summary>
+
+- [x] Create an awesome feature X
+- [ ] Do my homework
