Thank you for contacting Syncfusion support.
The Sub menu items will usually have a higher z-index and hence it will be displayed above the container <div> element. In your case, the <div> container must have a higher z-index than sub menu element or it must have overflow property to set as hidden. So, to fix this, you need to set a z-index value for submenu items higher than the <div> element or set the overflow property to visible for <div> element. Kindly refer to the following code snippet.
