Perform the following steps:
1. Select the corresponding component in the panel. If the component has a pop-up attribute, this attribute is displayed next to the lower right corner of the panel.
2. Make sure that the name of the pop-up attribute is consistent with the target name indicated in the right-side pane, and click the Delete icon.
3. You can also click the pop-up attribute at the lower part of the UI Studio to show or hide the pop-up component as needed.
