javascript - How to select optgroup -


is there way select optgroup?

it seems disabled time. have tried searching javascript solutions not find ones.

well can have example here: http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_optgroup

its more tag, tell options below. or caption.

if want select multiple ones might use jquery created select. mean custom one, or can use checkboxes , merge them in list select tag.

there no other way select 2 options 1 select element. each select must have 1 , 1 value.

other way add value each option, , seperate them using ,. there no option select optgroup way group options under or more label them.

i getting warning alert missing point, want click on optgroup , select value under it? think might condition!
