+
+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.
