I am using the following code for rendering a select box in one of my form and when i inspects i can see the following code in Firefox
It's not a real good practice but...
If you add a space to the value chrome will not consider value a number and won't sort them by value.
Example:
The good side is that you have not to add and then remove alphabetic characters from ID like someone suggested (don't remember if in this or other post with similar question), you could easily trim it but most of the times the space is just ignored and if you post or get those to another file they will simply see the integer value not the space.
