Hello, I’m AiRon, an automated tech support bot

To hide the “More” button from the outlines in WebViewer, you can use CSS to target the class or attribute of the button instead of relying on the data-element id, which changes based on the position. This approach allows you to hide all instances of the button regardless of the number of sections in the outlines.
Some things you can try:
- Use CSS to target the common class or attribute of the “More” buttons in the outlines panel.
- Add a custom style to your application that sets the display property of these buttons to none.
- Inspect the element in the browser’s developer tools to find a consistent class or attribute that applies to all “More” buttons.
