Is there a way to limit the max selected options in <select>

[Mihai Popescu]

Is there a way to select lets say max selected options from a <select> tag...
for example
I have a select with 150 options... but I want to select maximum 30...
I've tried with js onclick and onchange for select but the event is trigged only when I release the mouse button

Just to clarify, you're trying to select more than one option at a time but no more than thirty options?

yes, something like this
I can make a counter that counts every time I click on it... but some times the user can select with a click more than 30 options...
now I check every time onChange if there are more than 30 then deselect the last of them...
