 Q: How to scale `Gempyre::Bitmap`?</br>
 A: You can use browser's bitmap scaling by applying the bitmap as image and then using `Gempyre::FrameComposer` for draw. Look the following snippet:

 // name the image

 Q: How to do multiple `Gempyre::FrameComposer` in a single draw? My second draw is not visible</br>
 A: Do you call erase? See `GempyreCanvas::draw_completed above. You may also try to call your drawn in a `Ui::after` timer with 0ms delay, that should ensure the correct drawing order.
 
+Q: Why my dynamic HTML `<select>` does not work with numbers?</br>
+A: The UI select uses strings, and hence the values has to be _quoted_ strings.
+```html
+  <select id="show_tags" disabled></select>  
+```
+
+```cpp
+
+   Gempyre::Element show_tags(ui, "show_tags");
+   show_tags.remove_attribute("disabled");  // remove disabled
+   // dynamical add items numerical keys
+   for(const int value : tag_keys) {
