+
+```yaml
+  - name: all_smd
+    type: generic
+    exclude_smd: true
+    invert: true
+```
+The list will be expanded to R1 plus all the SMD components of the board.
+But suppose you want to select all the SMD components of the top side of the board,
+you could use `[[front | _kf(all_smd;all_front) ]]` adding the following filter:
+
+```yaml
+  - name: all_front
+    type: generic
+    exclude_bottom: true
+```
+
+Note that we use `;` as separator because `,` is the separator in the list of references.
+You can also use the `!` (not) operator, like this: `[[front | _kf(all_tht;!all_conn) ]]`
+This will select all THT components that aren't connectors, assuming you provide the
+correct filters. Here is an [example to try](../tests/data/with_filter_html.md).

+# Demo population with filters
+
+This is an example of populate output using KiBot filters.
+
+- [[front | ]] This is the front side of the board we are populating
+- [[back | ]] This is the back side of the board we are populating
+- [[front | _kf(all_smd;all_front) ]] First, populate all the SMD components on the front
+- [[back | _kf(all_smd;all_back)]] Now do the same for the back
+
+Now that you have all SMD components start soldering the THT components.
+But leave the connectors for the last step.
+
+- [[front | _kf(all_tht;!all_conn) ]] All THT, but connectors
+- [[front | _kf(all_conn) ]] Connectors added
+
+And here is the finished board
+
+- [[front | ]] Front
+- [[back | ]] Back
+
+## Conclusion
+
+You can add groups of components matching a filter.
