i want to know how can we select more than one option from a select box like given below:
Ordinarily an HTML form will allow you to Ctrl-Click multiple options from a combo box, if you use the "multiple" option in the tag.You can also use "Shift-Click" for a range of values.
But the interesting question is how can you implement this so that more than 10% (estimated) of users can figure out how to use it?
