+To ensure that Sprotty elements (such as nodes, edges, etc.) are always in the foreground, 
+you would generally need to modify their layer or z-index in the Sprotty framework, 
+which relies on SVG (Scalable Vector Graphics) elements.
+
+Here’s what you can do:
+
+1. **Set the SVG z-index:**
+   You can explicitly set a higher `z-index` for the elements you want to be in the foreground. 
+   In Sprotty, elements are typically rendered in layers based on their order in the SVG document. 
+   By assigning the desired elements a higher `z-index`, 
+   they will be rendered on top of other elements.
+
+   In the `SModelElement` (or whatever your model element type is), 
+   ensure the `zIndex` attribute is set for the foreground elements:
+   
+   ```typescript
+   const foregroundElement = {
+     id: "elementId",
+     type: "type",
+     zIndex: 1000 // Higher value to push it to the foreground
+   };
+   ```
+
+2. **Ensure correct layer ordering in the rendering code:**
+   If you're directly controlling the layer order in the rendering code, 
+   make sure you render the foreground elements last, after other elements.
+
+3. **Layering in styles:**
+   If you're using styles to control the appearance, 
+   you can target elements using CSS and set `z-index` directly.
+
+   For example:
+
+   ```css
+   .foregroundElement {
+     z-index: 1000;
+   }
+   ```
+
+4. **Using Sprotty's `zIndex` in component code:**
+   If you're working with Sprotty’s specific components, 
+   make sure that the foreground elements are being added to a 
+   layer or group that has the highest stacking context. 
+   This ensures they appear on top of other graphical elements.
