Issue Summary

The Expand/collapse button are not  programmatically defined expandable state.

Steps to Reproduce

1. Edit the page, and add  "UI Expand" and update the page.
2. Navigate to the button and observe keyboard support is missing.
3. Listen that the expand/collapse state is not announced for the button.

Actual Result

 The Expand/collapse interactive elements are not operable with a keyboard. The role and state of the buttons are not programmatically determined for screen reader users.
This made it difficult for keyboard-only and screen reader users to access the expand/collapse functionality associated with mentioned buttons.
 

Expected Result

Apply the following changes:

• Code the mentioned interactive elements using <button> tag.
• Set the “aria-expanded” attribute to “false” for the button when the button is in the collapsed state.
• Ensure that the value of the “aria-expanded” attribute changes on user interaction via scripting.
